Description


The new CYBEX Eternis S with SensorSafe is the only seat your child will need from birth and beyond. With three modes -- rear-facing, forward-facing and booster, this All-In-One Convertible Car Seat is designed for use from birth up to 120 lbs. The Eternis S with SensorSafe integrates important safety technology into the chest clip of the car seat to alert when unsafe situations arise. The alerts are provided through a vehicle receiver and the caregiver’s smartphone. The Eternis S with SensorSafe alerts when the driver accidentally leaves the child behind secured in the car seat, a child unbuckles their chest clip while the vehicle is in motion, the back seat has become too warm or too cold and when a child has been seated for too long —all through a user-friendly app, that also provides guidance on installation, how-to videos, FAQ’s and more. Additionally, the Eternis S with SensorSafe offers an adjustable Linear Side-impact Protection (L.S.P. System), which absorbs up to 25% more impact forces in the event of a near side impact collision* and a patented 3-position reclining headrest, which helps prevent the child's head from falling forward while asleep, guiding the head and neck into a safe position. These features, combined with a steel reinforced frame for strength and durability provide advanced child safety protection and peace of mind.
  • Rear-facing from 4 lbs. to 50 lbs. Forward-facing from 22 lbs. to 65 lbs., Belt-positioning Booster from 40 lbs. to 120 lbs.
  • 5-point safety harness with SensorSafe Technology integrated in the chest clip (not used in Belt-positioning Booster mode)
  • Adjustable Linear Side-impact Protection (L.S.P. System) absorbs up to 25% more impact forces in the event of a near side impact collision* (*when compared to the same car seat without L.S.P. extended)
  • Patented 3-position reclining headrest helps prevent the child's head from falling forward while asleep, keeping the head and neck in a safe position and ensures a comfortable sleeping position
  • In-seat recline provides correct ergonomic positioning and extra legroom, allowing your child to safely ride rear-facing longer
  • 12-position, height-adjustable headrest with an integrated no-rethread harness for protection that grows with your child
  • 6-position one-hand adjustable recline for the best fit to your car
  • Magnetic buckle holders for easy entry and exit from the seat
  • Removable newborn inlay provides additional support for very small babies (4 lbs. to 11 lbs.)
  • Removable cup holder can be positioned on either side and is dishwasher safe for easy clean up
  • Cozy harness pads and 2-position padded buckle for comfort
  • Steel reinforced frame provides strength and durability
  • Energy absorbing shell and base help reduce the forces felt by the child in a collision
  • Dual Belt adjusters to ensure a tight fit
  • Dual-level indicators to help ensure the proper angle
  • Innovative one-pull LATCH removal system
  • LATCH Connection storage provided under the seat when not in use
  • Ergonomic design in CYBEX’s iconic Gold Design language
  • Designed and engineered in Germany

How SensorSafe Works:

Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to act quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive. For ease, just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind.
  • Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
  • Alerts through the caregiver’s cell phone if the child is left behind in the vehicle secured in the car seat and then alerts the designated emergency contact if the situation is still not remedied
  • Emergency contact receives GPS coordinates of the vehicle’s last known position
  • Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled their chest clip while the vehicle is in motion
  • Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
  • Provides warnings to the caregiver when the child may have been seated for too long and needs a break
  • Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
  • Only one install needed if receiver is kept plugged into vehicle’s OBD port
  • Helps ensure proper use by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the SensorSafe app
  • App can monitor up to 16 chest clips on a single platform
  • App download available for Android and IOS

Specifications:

  • Measurements: Forward-facing (Fully upright) H 25.5” x W 20” x D 25.3”
  • Weight: 26 lbs.
  • Use from Birth up to 120 lbs. or 57 inches, following the directions in your user manual

Great seat, not so easy to install
October 11, 2019
The car seat is beautiful, is comfortable but is not easy to install. The straps are difficult to adjust, tightening the latch system is hard. The sensor safe only works in United States, if you go in a journey to another country the system is not going to work.

Very nice features, minor superficial complaints
August 17, 2019
Installation: We installed the carseat forward facing with lap and shoulder belt. It was very straighforward and simple EXCEPT the instructions for the belt lock feature were lacking (no pictures, no instructions on how to put the belt in, and I'm pretty sure you don't need this feature if you have a seatbelt that locks). We ended up not using it.
Features: The cupholder is pretty dinky, you just slide it on one of the sides and it does not seem like it will hold up to toddler use, and it is oddly slanted (using recline 5). I love that the shoulder straps move up with the headrest and do not require re-threading. This makes it VERY easy to resize as your baby grows. I also like that there is a storage compartment for the top tether belt if you were not using it. The Linear Side-Impact Feature sounds like a good added safety feature though I hope we never need to know.

Overall this seat seems comfortable for my son, easy to us on a day-to-day basis

The technology of this car seat is amazing!
It’s definitely a game changer.

I would definitely recommend to my friends and family

I first received my car seat and there was some kind of burn mark ok the exterior of the car seat. After reaching out to customer service I got a replacement. Amazing customer service!

PERFECT for my 4month infant and my 3yr toddler!
July 25, 2019
This car seat is great for infant to toddler. I have a 4 month old daughter that I used the car seat for 2 weeks. It was great for a permanent rear facing seat. I really enjoyed the Magnetic Buckle Holder!!! Having a small child and having to place in the seat is difficult and especially when the straps lays under them. I also used this seat for my 3 year old daughter. She was in love with how roomy and comfy(squishy) it was. The adjustable head rest was nice for her. Also being able to position the car seat to be specific to your child is very helpful in taking long car rides. NO NEED TO ADJUST THE HARNESS just slide the headrest!!! Super quick! Also easy to install LATCH system but EASIER to remove with the one pull red strap.
This is my 1st Cybex brand product or even hearing about the brand. This car seat has really opened my eyes on what nice quality details and safety features Cybex offers.

The Most Perfect Carseat!
July 23, 2019
We love this carseat. We are foster parents and have been on the hunt for a safe reliable carseat that could comfortably fit a large age range of children, and the Cybex Eternis S fits the bill. For a carseat that works from infant through 120 lbs (WHAT??!!! thats AMAZING), its affordable and stylish and comfy as all get out (I wouldnt know, but the kiddos seem to love it). My favorite small little detail about the Eternis S are the magnetic seatbelt clip holders- this has been a lifesaver when transfering a sleeping baby without waking them by having to pull up the seatbelt straps from underneath them. And it was SO easy to install! We started with a cybex infant seat and trust the brand, and have upgraded to this all-in-one Cybex Eternis and we wont look back. We are Cybex fans for life!

Extremely high quality. Gives me peace of mind.
July 21, 2019
The most important thing about an infant/child's car seat is Safety in my opinion. The Eternis is made extremely sturdy and all of the parts on this car seat glides/snaps smoothly and seamlessly. You can tell that they did not skimp on a single detail- including the packaging box that it comes in. (I've had other car seats delivered in a loosely packaged box without any foam protection or padding that keeps it in place. So the box is not only bent but the car seat inside it has been tossed/bumped around!)

So the attention to detail not only makes me feel like I have a high quality product, but it gives me assurance that the car seat is going to hold up and do it's job in the event of an accident. I love the LSP (Linear Side-Impact Protection) that is built into this seat too. Even though the middle seat is supposed to be the safest to put your car seat in, the LSP seems like it would give extra protection that my previous car seats didn't have even if it's installed on the outer sides. I have two different car seats installed on each side of my backseat. And honestly, it's tough deciding which child to put into the Eternis because I feel like I'm favoring one child over the other and in the event of a car accident, the other child may not be as safe. It's so stupid and silly but I really do feel that way and I'm thinking of buying another Eternis and donating my other car seat because of it. LOL.

The only drawback I could see about the Eternis though, is the size/width. You really can't put 3 car seats in a row with this. However, 3 in a row is hard to do with most car seats and I think the Eternis is more for people who are looking for Style and Durability or Safety. Not necessarily Space savings or Lightweight/Travel friendly. So just think about what's more important for your specific needs before you make a decision.

Convertible carseat
July 21, 2019
My family got this car seat a couple of weeks ago and we are already so happy with it. I needed a car seat to put in my husband's car that we could use with my 3 year old but also with my 5 month old. This car seat can be easily switched from being forward facing in a more upright position for my toddler to being rear facing and inclined at the right angle for my infant. The look is amazing and completely sleek looking.

Best car seat ever!
July 18, 2019
We've had this seat for about a month. I was AMAZED at the attention to detail. My favorite feature is that everything has a built in storage area. Especially for the user manual! It fit's right in the back compartment. Same for the back latch, and for the latch system. I also love the weight of the seat. It feels like a safe place for our little ones.

All in One Luxury Car Seat!
July 17, 2019
I have had this car seat for about three weeks and so far I love the look, features and my daughter seems to be more comfortable in it than her old car seat. We went on a road trip and she did not fuss which is a big win for us! My initial thought was it was sleek and modern, so much my husband instantly wanted to switch out seats with me and put it in his sports car. I love the soft padded material around the shoulder supports and leg buckle. I was also impressed with the back support that automatically adjusts when you pull the head rest up and down. This seat also has Linear Side-Impact Protection which is hard plastic that can be set on each side and is designed to absorb impact during an accident.

Installation was a bit difficult. It took about 30 minutes to install the first time and that was after reading the instructions. The issues I ran into were understanding the proper routing for the lap/seat belt for the rear facing configuration. The seat was loose and it took a moment to figure out how to route the belt through the belt locking feature. Subsequently, the seat was extremely easier to install.Once installed everything was easily adjustable including the tilting mechanism and moving the headrest.

Overall, I love the car seat and would definitely consider purchasing this seat for my next child. It is definitely top of the line and superior in many ways.

Pros:
The seat sits firm and doesn't slide around in my vehicle (GMC Terrain).
Spacious seat
Shoulder cushions are comfortable
Cup Holder easily clips to either side of car seat

Cons:
Initial installation becomes labor intensive due to ambiguous directions.
The buckle across the chest is a little hard to unclip which may ease up over time.
Material is not removable (spot cleaning can be difficult)

Such a comfortable fit
July 16, 2019
I really really love this car seat! My 2.5 year old is so comfortable and actually loves sitting in it. I think my favorite feature is how easy it was to install. He is still rear facing, and I hate struggling to get the car seat hooked to the tethers. This made it so easy to switch between cars and get a good tight fit every time we had to install it. I also loved that you can access the tethers by unsnapping the lining of the car seat. It made it so easy to thread them through properly and make sure they were not twisted.

I also really love that it offers a head recline. We have not used it much yet, but when my youngest gets a little bigger, and out of the infant seat, I can't want to have that option for her so she does not slump foreword! It is easily adjustable, and very easy to get the right fit/recline in the car.

I would highly recommend this for ease of install, ease of adjustment, and the comfortable feel for my kiddo!

Beautiful and functional car seat!
July 16, 2019
I have been using this convertible car seat for a few weeks now and I am so glad I went for it. I'll start by saying that it is a very well made car seat and of course it is heavy, but that only makes me feel safer while driving my toddler around, and once it's installed is not going anywhere. It has a lot of padding and seems very comfortable, even the buckle has some around it to avoid marks around my babies thighs when she wears shorts or bathing suit. The adjustable head rest makes this car seat extra safe! It reminds me of a race car and how protected their head must be.
I picked black color and it might be slightly "boring" but I like how you can't really tell there have been some water spills, and it is easy to clean.
It took me a little while to learn how things work (I am slightly technology impaired) especially with adjusting the head rest and making sure it was in the right position, but once I got it it was great. The straps slide very nicely as well and the small places to hook them are such a nice feature!! So helpful when you have a sleeping baby that you need to put in or take out of the car!
Overall, this car seat has everything you need and nothing you don't. Plus did I mention how safe it is?

We have the Cybex Gold Eternis S All in One Carseat in Lavastone. I feel that Cybex thought of EVERYTHING when they created this product!! The installation of this carseat was so simple! My husband and I were able to install it together in about 10 minutes tops. One thing that really sticks out with this carseat is that my child can rear face up to 50 pounds! That's a huge deal for me as children and safest rear facing! I love that my child has so much room in this carseat and is still safe with the linear side protection and the steel base (the highest in safety quality). Some other amazing features of this carseat are the tilting headrest so that my daughter's head doesn't flop forward when she falls asleep and the magnetic holders on the side for the safety clips. This carseat is top notch and WELL worth the investment!

This carseat is amazing, it came all together and ready to go. I will say it is heavy but totally fine. I had it installed in my Tahoe and it worked wonderfully. I do like the L.S.P. system which puts my mind at ease for safety if anything was to happen. I love the color and fabic was soft. Im happy to know it has a ten year life span which is great. A all in one for all stages of my childs life. I even liked the fact it came with a cup holder. Adjusting the seat in the car was easy to do, plus, it had a leveller for adjusting to where it needs to be in safe zone. I definitely will recommend this carseat.

Love for my older child!

I decided to use this seat for my 7 year old because of the tilting head rest. My son fits well in this seat and he told me it is more comfortable than his previous high back booster. The tilting head rest is so nice for him to be able to sleep in the car. What's nice value for a convertible car seat from basically birth to booster. The only thing I would change is add a ratchet system to install it.

Great for toddler!
July 12, 2019
This is a very well made car seat. It is heavy, but sturdy and the fabric is soft, good looking, and no piling yet!

The headrest and straps are very easy to adjust. The straps glide smoothly and it's super easy tightening or loosening them. With the headrest in the lowest setting the seat back folds and sits awkwardly in the seat. As the headrest is raised the seat back fits much nicer. I achieved a good fit for my 9 month old. The seat doesn't feel very padded- the seat back actually feels a bit hard but my daughter falls asleep in it so I imagine it isn't that uncomfortable.

I love how easy the belt install is in my car. The multiple reclines, level, and labels on the seat made it quick and easy to install (rfig) first try. Hoping ffing will be the same!

Exquisite Safety & Design
July 10, 2019
I currently have the Cybex Cloud Q plus infant car seat and was looking to upgrade to a car seat that could stay with my little one throughout his years. I am consistently drawn to the Cybex brand because of its powerful combination of safety and design. The Eternis S has both, and I found it easy to install as well as safe, comfortable, and stylish.

I installed the Eternis S using the latch system and rear-facing option. The latches are in a compartment underneath the seat and the instructions in the booklet were easy to follow, esp. the visuals. I also like that there's a device on the side with a bead so you know you've installed it correctly (e.g. the recline) for both forward and rear facing options, based on your child's weight.

The linear side protection was so easy to use (just push a button!) and is an added element of safety. Beyond the ease of installation, some features I enjoy include the following: the reclining headrest so that baby/child's head is back with airway open; the soft padding; and the ability to remove and wash the upholstery on the seat. My one criticism is that for the seatbelt, particularly the bottom buckle, you do need to have one hand on the front and back to forcefully push the red button so the belt releases.

Overall, it's reassuring to have my child in the safest car seat while also turning heads with the Eternis' innovative style. I look forward to transitioning to the forward facing option when my little one is big enough, and having this car seat for the long haul. .

Best carseat I've ever owned!
July 10, 2019
I've had 3 children, and went through a few carseats, I can honestly say this is the best carseat I've ever owned! It has such a nice amount of padding! Makes for such a comfortable car ride! I got it for my son who just turned two so I have only used this forward facing. Feels so sturdy and safe! The head rest tilts back so when hes asleep his little head doesn't flop forward, like it would in any other seat! I like that the cup is removable, so it's easy to clean or choose which side to put it on. Although, if I had one complaint I wish it had the cup connected to the front of an arm rest. Only because I have two seats next to eachother and there isn't much room for me to squeeze the cup on the side by my daughters seat. The feature on the bottom to make sure the seat is at the right angle is so nice and easy to use! It was super easy to install. love the side impact safety as well! My daughter who is 4 sat in it and was like oh my gosh mom this seat is so comfortable, I want to trade lol
I definitely recommend this carseat!! I recieved this carseat in exchange for an honest review.

Piece of Mind
July 10, 2019
The Cybex Eternis S All-In-One Convertible Car Seat is going to be the only seat my 3 month old son will ever need because it grows with him.  It moves from rear-facing to forward facing to a booster seat as he gets older.

The car seat was fairly heavy due to the steel reinforced frame which gives me a peace of mind knowing that if I am in an accident that I have one of the best durable materials surrounding my child.

This seat came with an additional protection function called Linear Side-Impact Protection (LSP).  It was an easy to push button on the side of the car seat which then popped out a hard piece of plastic toward the door which is designed to absorb up to 25% more impact forces in an accident.

The headrest in this seat had 12 different positions!  I always worried with my first child that her head would bounce around and fall to her chest once she fell asleep.  Using this seat for my son I can worry less because it has all of these positions that you can set the headrest at.  Some settings are designed at these inclines especially for when they fall asleep.

It was easy to install using the anchor clips and that they click released.  The tightening straps could be shortened or lengthened effortlessly.  I did find that the labeling could have been better in the manual/on the car seat because I was looking for the exact words of rear facing belt on the car seat to slip the seat belt through and I was not able to find it.  The headrest was a bit difficult to adjust at first because you have to pull up on the release and push/pull the headrest at the same time.

After a very long day of car riding my son seemed to nap well in the seat and not be as fussy during awake periods due to all of the extra padding and positions you can have in this car seat.

Comfortable, easy to install seat
July 10, 2019
We are loving this seat so far! My son says his favorite part is the padded lower seatbelt - I think that the bottom part of car seat seatbelts can be very uncomfortable for little boys, and this one has a nice soft padding to protect. I was able to install it very quickly, and get a secure in style. The seat is sleek, and easy to buckle. I love that it can convert to the high back booster, which we will be doing in the next several months.

Great safety features
July 10, 2019
The Eternis Car seat is a great car seat. I feel like this car seat is so Solid! The added safety features like the linear side impact system are great for peace of mind. One of my favorite features is the magnetic strap holders. No more having to dig for the buckles or hold them out of the way while putting baby in the seat. The reclining headrest is also nice but not usable during the smaller infant stages so I can not
tell you if my child likes it or not. The aesthetic of the seat is very sleek looking. Really the only cons to this seat have to do with the harness. I felt like the buckles were a bit cumbersome. They work, don't get me wrong, but It takes a little more effort. Also the tightening strap was awkward in the rear facing position. The opening was too close to my car's seat and made it difficult to pull. Those are really only minor things though. Overall I think this is a fantastic car seat

Easy to install, great safety features!
July 10, 2019
I love this car seat!! The first thing I noticed was how soft the fabric is. It appears so comfortable and luxurious. Although heavy, the seat was easily placed in the car and adjusted for my 15m old. The level at the bottom made it easy to ensure it was adjusted properly. My baby is very comfortable. The wings in the head make a little car nap easy with no "head bob". The design of the seat is also great with side impact safety features and has a firm fit on the 5 point harness. I would definitely recommend!!

Nice, comfy seat with a few great features.
July 8, 2019
This car seat replaced another that we had. My child is EXTREMELY comfortable in it. She now is willing to take longer car rides. It is also very easy to get her in and out of this seat, which is nice. It has some nice features that I like and some that can be better but we have no real issue with.

Pros: The magnets that hold the buckles up are very useful. The easy in which we can tilt the seat is nice. The pull-through to tighten the latch buckles made tightening it easy. The button to loose the straps is the best we have seen, most are either difficult to find or press the "wrong" way, this one makes loosing the straps very easy and removing my child from the seat very easy well. When the head rest goes up it adjusts the straps automatically. The head rest tilts forward and back, which greatly aids to my child's comfort.

Cons: The head rest is a bit wobbly, but I am not really worried about that. There is no way to remove the seat cover, so cleaning it will be difficult. Somehow the straps came loose and I had to retread them to through the seat, I think this was just bad luck though, I was able to do this with relative ease.

Overall: Not being able to remove the seat cover to clean it might be an issue, spot cleaning it is easy enough though. If you can live with not removing the seat cover, then this is a very nice car seat that we expect will last for many years. We are really happy with the comfort, which is top notch and the features like the magnets to hold the straps and the button to loosen them are a real plus.

Excellent Car Seat
July 6, 2019
I've had this car seat for about a week and it's such an excellent car seat! My 2 year old actually enjoys sitting in his car seat and I can see that he is comfortable. The safety features are excellent. The belt clip is easy to use, easy to get my son in and out of. The sensor safe app is helpful, but something we have to get used to using since this is the first car seat that actually has an app. Installation was a little difficult, but we eventually figured it was my car's latch system at fault. I drive a midsize suv and the Eternis is a little on the big side, but there is enough space for 2 passengers in the back. I'm very happy with this car seat and it's features. This car seat exceeded my expectations compared to the other brands that I've tried! Thank you Cybex!

Fits very nicely in our Subaru Forester, was very easy to install and get nice and tight using the latch system, both sides can be tightened and I like that a lot. Feels very very sturdy and our daughter fell asleep on the way home the second time she road in it so it also much be very comfortable!

High quality, flexible use, lots of features
June 29, 2019
This is a high quality car seat that will last through each stage. It's well made, and has cool features like side door impact protection, a cup holder my kid can reach, flexible headrest, comfy padding and a nice shape, etc. my only downside is that it's super heavy- not a travel car seat at all- this one will live in our car and we got a cheap, light one for travel.

One and only car seat you will ever need!
June 28, 2019
I got this car seat this week and am amazed as it truly does meet the needs of my children from rear facing to booster. Most important it is easy to transition and install. The seat fasteners are quick and easy as they can be easily hooked and unhooked. (All I have to do is pull on a cord and they come undone no more pulling till I can't feel my fingers.) This latch system should be on all your seats! I love how how I don't have to remove the harness straps to transition it to a booster and it is still comfortable at the same time. My children love the seat and have been fighting over who gets to sit in it.

Love the brand

We had a Cybex infant car seat and it worked out great for us. I was thrilled to hear they also make convertible car seats. We ordered the Eternis S and it has worked very well. It’s very comfortable, fits our car perfectly, and love the head recline option! Not a lot of car seats offer this. My son’s head doesn’t move forward anymore, such a relief for his neck!

Loving everything about it
March 31, 2019
I'll admit I was nervous about transitioning our not-quite-one-year-old to a convertible car seat and about learning to install a new one, just when we'd gotten good at the infant seat. But this one was super-easy to install (we used the LATCH connections, not seatbelt), and the baby seems to be very comfortable. A few days after we installed it, we had a 6-hour round-trip weekend car ride, and it looked like he enjoyed having the extra space this seat provides. The adults in our family are appreciating the sophisticated, subtle design aesthetic, in shades of gray, and the ease of adjustment. The mechanism to tighten and loosen the belts to get baby in and out works easily and smoothly, and the system to adjust the height of the headrest couldn't be simpler. It's connected to the top of the shoulder part of the straps, which makes it super fast to adjust them higher as he grows. On the road-trip weekend, we had our two-year-old, much larger nephew in the seat at one point, and we could set it up for him and then back to fit our son in a flash. (Just to note: this seat is substantial, best to install and then leave in the car. It's not the kind you'll want to put in and out, switching between cars.) The second weekend using it, on another roadtrip, we set up the SensorSafe function, too, connecting it to the car's computer and downloading the SensorSafe app so we could connect the seat to a smartphone. That was all pretty seamless, the hardest part being to find the jack for the piece that connects to the car's computer. From there, the seat connected to the car and then to a phone easily. Now, there's a chiming sound when the car turns off if the seat is buckled, reminding us that baby is still buckled in, and, once he's old enough to figure out how to unbuckle himself, it'll warn us about that too, which will be great. The app also shares the temperature in the area immediately around the seat. We're very much looking forward to using this for years to come, from the rear-facing seat we currently have it installed as, to front-facing and then converting it to work as a booster.

So far so good

We’re a fan of Cybex baby gears and when this all-in-one car seat came out it was a must for us. We got two for both of our kids to ride in our SUV and they are so happy with it. They seemed comfortable enough to nap happily for long car rides. Well made, safe and well designed.
Cons
  • I wish the magnets on the side to hold the seatbelt up are stronger.

Has so many features which will make your child safer and your life easier.
The magnetic belt clips and SensorSafe app were the features that gave this seat the advantage over comparable products.
The build quality and materials put into this seat struck me straight as I pulled it out of the box.
Overall I am very satisfied and give an extremely positive recommendation.

February 6, 2019
I am so pleased with this car seat. It has a nice, sleek design and the color choices work well with the interior of my car. I feel much more at ease with my son safely secured in this car seat, as opposed to the other seat we had prior. And he just always looks so incredibly happy in his new car seat! It's like it was a huge confidence booster for him. He loves his new look and he also looks to be more comfortable. Also, there was no complicated assembly involved and routine adjustments are simple and easy to do

Luxury Carseat

I want my child to have the best of everything and this car seat is certainly the best one on the market for several reasons. First, the material is soft yet sturdy and most importantly the design itself makes it easier for bigger babies, like mine, to be comfortable during long rides. There is padding with infant inserts too which makes it amazing to use from the time the baby is born up until they are ready to be out of a car seat! And...BEST OF ALL, I CAN WASH THE FABRIC that comes off!!! In addition, it was easy to install and is easy to adjust. What I love is that the headrest tilts which helps the baby stay in the correct position while sleeping. Also, I love that eventually when the baby is big enough to be front facing, the seat belt will go through the red clip. Moreover, SensorSafe is really cool with the manuals on the app & temperature and unbuckling notifications right on your phone. It's a great parent back-up and low-jack since it tells you where the car seat is! I'm really impressed with the magnetic buckles to get the baby in and out of the car seat easily.....THIS CAR SEAT HAS IT ALL!

This carseat is amazing! My toddler loves it and she has always hating getting into the carseat. The headrest is very comfortable for her and she sleeps well in it. I was even able to keep her rear facing longer because of the positioning and extra leg room. Overall it is a wonderfully made car seat with lots of amazing features.

Strong Car Seat for Toddlers
January 25, 2019
First of all, i have to say that i was looking through so many car seats and read so many reviews for my little one. When it came to car seats one of the most recommended brands through family and friends was Cybex company. To be honest i never heard of the company until recently.
I was very hesitant to order Cybex Gold - Eternis S with sensor safe car seat.
The car seat is great. It is not too bulky and it has a great color. The material on the car seat is washable, which i love.
The installation itself was fairly easy. You just have to read the manual and you have to make sure that the back of the car seat stripes are locked properly.
What i love about this car seat is that it has two red handles where the child head is and it allows you to adjust the cushion for the head base on the child's height. It also accommodates your child as their grow and you can change their sitting position.
The safety belt is easily adjustable and and i love the sensor safe option that has built in to the chest clip. If it happens that your child tries to untie themselves or there are some unsafe movements in the car seat the system will alert you via app that you install on the phone.
I also loved that on the left side of the car seat there is something called Linear Side Impact protection. If you are happen to be in the car accident this button that is on the side will activate to provide extra safety for your child.
The car seat is very safe and sturdy , but it is also child friendly in terms that you can wash the fabric and remove the cup holder and wash it in the washing machine.
I would definitely recommend all parents when it comes to child safety not to look at the price of the car seat.
Look at it's overall safety .
I will keep using all Cybex products for my little growing family.
After all, what matters to me is the quality of the product which will keep my family safe.

Great Protection
January 25, 2019
The carseat is perfect for baby travel. Easy to install and works perfectly as described. The 3-position reclining headrest helps put the baby in a comfortable position. Also, it doesn't take much space, so the person sitting in the front passenger's seat can have enough leg room. The pads are very cozy which make the baby comfortanle. The SensorSafe feature alerts you when the ignition of the car is off so you dont accidentally leave forget the baby in the car.
The only downside to this carseat is that the base is not detachable which makes it difficult moving the baby when sleeping without waking them up.

Stylish!
January 23, 2019
Very sleek and stylish looking. Both of my kids fight over who gets to sit in it as they find it very comfortable. Only 4 stars for me because installation was a little difficult and the sensor chest clip is very stiff and hard to release. Hoping it gets better the more we use it.

Great Quality Car Seat
January 21, 2019
My first impression upon taking this car seat out of the box was that it is made very well, and feels high quality. It is heavy-duty (heavy!) and very comparable to our older car seat of a different brand. The seat is nicely padded and seems very comfortable for my two-year-old who fits in it well. You can tell a lot of thought was put into the design as it has newer features that we didn't have with our old car seat such as the "linear side-impact protection" and detachable cup holder. We were also impressed that it has a "sensor safe" chest clip to alert you that a child is still in the vehicle. It pivots easily on its base for adjusting the angle of recline. I did find the installation of this car seat to be confusing right off the bat because we so enjoy the "click tight" method of car seat installation and this doesn't have that. From reading the user manual and after practice, the installation has gotten much easier. I definitely feel comfortable with the safety of my children in this seat. We've been impressed overall with this car seat, and other than lacking "click-tight" it's perfectly equipped with everything you need.
