The quality I expected!

I’ve been using Britax car seats for 15 years and I’ve never been disappointed. I really like the ease of installation of this seat. I bought this knowing it will last my 4 year old another 4-5 years.

Great Product. Great price.
January 21, 2021
We bought this as a second seat for the second car. We already own a Frontier Clicktight, but I didn’t really want to pay the Clicktight price this time, and I didn’t like how every option I saw industry wide was this knit fabric that going to pill like crazy. This seat has woven sides like my frontier and the grey pattern is a more durable knit.

I understand why Clicktight is great for their convertible seats and people like us who move and switch seats often. However high backs are super easy to install without that feature. If you use the latch system or the seat belt, paying double this price for Clicktight isn’t worth it to possibly save one or two seconds. It’s so easy it kinda annoys me I paid more than this for the frontier Clicktight. Oh well both seats in my car are the vector print which I love.
Anyway this seat is basically the same as the $209 seats without Clicktight, but better fabric IMO. I’m thinking about switching out the crotch buckle to the hook type like on their $99 high back booster line when my guy is a bit bigger and ready for just the seat belt.
Basically if you don’t want to shell out a ton, but want a great seat this is a great deal for Britax quality. We paid $~$160 with tax instead of ~$300+.

Hard to secure child and head support jiggles
December 16, 2020
I was excited about another Britax car seat since I lived our previous one. This one does not compare to others in the price range. The headpiece vibrates causing a constant background noise. In addition, it is really hard to get the straps tight on my son. I have the pull on the strap several times before it is tight.

Super easy to run the belt through the bottom to click into the backseat. Along with the clip to tether the seat to the hook at the top, it was about a minute to secure this in the car. Very easy!

We have had our daughter in a very basic infant-to-toddler convertible carseat since 12 months or so. This seems very sturdy and much more comfortable for the child. So far everyone seems pleased. Easy enough to install and buckle / unbuckle.

Overall this isn't a terrible booster seat but there are some things I do not like about it. When the headrest is fully extended the top section of the head rest can rattle as you drive especially if you don't have your child in the seat. Also the shoulder straps are difficult to pull tight enough, although this might become easier over time. I do like that the seat has cup holders on both sides. I also don't find it to be too wide so you could put another seat next to it depending on your car.

I love this car seat. It’s comfortable. My son has cerebral palsy and sitting in the car for long periods of time can be painful but this seat is very comfortable for him. It’s super easy to install. This is the second one of these seats I have bought. ( I got one for my daughter as well.)
  • Easy to install
  • Easy to clean
  • It?s really heavy not ideal if you have to move it from car to car.
  • Adjusting can sometimes be a pain and the straps can get twisted

This seat has all the best features to make it easy to use. I’ve had a tough time finding a seat to fit in our Teslas and this is hands down the best in the FC harness to booster category. The only thing that would make it better would be to make it eith a backless booster option.

I did a lot of research before I decided on the britax dualfit carseat. Very few bad reviews that I found and a good price point. It came in minimal packaging which it is nice we didn't end up with tons of styrofoam. It was easy to install. My 2yo loves it. I have a smaller backseat in my outlander and it fit well. I've only had it installed for a short amount of time and so far so good.

Well thought out carseat!
August 13, 2019
I was so excited to get this Britax Dualfit carseat as Britax had such a great reputation for well made and safe carseats. This carseat is no exception. With the Safecell impact protection, impact absorbing base and 2 layers of side impact protection I know this seat will effectively protect my son. I love how well thought out the construction is. It has a steal frame, easy adjusting straps and my favorite feature, the V-shaped tether. The V shape is to minimize the movement in a collision but I found it also has the added benefit of fitting over the headrest and therefore minimizing the wear to my car. This seat is streamlined and has hidden compartments to store the latch hooks and belts. Nothing hangs off or out; there's a place for everything. I was able to install and adjust the seat for my 4 year old son in under 15min. The instructions and diagrams on the side of the seat were very easy to read and understand. My son says it's "super comfy" so I'm very happy with this seat. Thank you to the weeSpring Parent Panel for providing me this carseat for my honest review.

Really Great Harness and Booster Combo
August 12, 2019
As a mom of two with a growing 5 year-old, I realized that I needed to move my son from his convertible carseat to a booster seat but had no idea which seat to pick. My son had been in his convertible car seat since his first birthday, I had not been carseat shopping in a while so I jumped at a chance to review the DualFit Harness-2-booster seat by Britax. First of all, I really do love Britax seats. They are durable, they feel rock solid in the car when installed correctly, and they're comfortable, or so they seem at least when my kids take naps in them. This car seat was no exception. Some of my favorite things about this seat were, the fact that it was a booster AND a harness system. I really feel more comfortable having my son in a harness system for as long as possible but he was really ready for an upgraded car seat so this one allowed me to have both. I LOVE that it has two cup holders just built right in, because his last seat did not...and it was a pain to hand him his drink every single time. As far as installing the car seat. I don't really think installing any car seat is easy, it's definitely not my favorite task of the day when I have to move one. That being said, this one wasn't so bad. The manual was helpful and easy to follow. The harness adjusts with the pull of a handle with no rethreading required, which earns major points for me. I had to move the lower buckle to the more forward position which took a little more manual searching, but I eventually figured it out, and I like that it has two options for that buckle. I also really love the botton release on the latch anchors that many Britax carseats have because it makes uninstalling the carseat a thousand times easier. The number of times that I have sat and fought a latch anchor that I can't get to release still haunt me. I also appreciate that this seat still has side-impact protection around my child's head. My biggest complaint is that the headrest squeaks and wiggles when I'm driving and my son is not in it. but overall, I would recommend this product.

Thank you weeSpring Parent Panel for giving me a chance to review this product.

Excellent Choice for the Price Point
August 12, 2019
Thanks to weeSpring Parent Panel for providing me with the Britax DUALFIT, harness high back booster seat in exchange for my honest opinion. As parents of a 3 year old and a 1 year old, we have tried our share of car seats, from the infant car seat to the "all in one" style of car seats. This was our first time trying out a car seat made specifically for an older child. There were multiple things to like about this car seat, and a few concerns detailed below, but for the price point, this harness high back booster is a very good choice.

The Britax DUAL FIT has a slim, but comfortable and sturdy design. The installation was easy with the quick click, lower anchors. However, the construction of the tether hook at the top of the car seat seemed to make it more difficult to properly tighten the strap. The design of the backrest made it easy to adjust the height of the chair to my child's specific requirements, and the narrow foot print of this car seat allowed plenty of leg room while still being a comfortable ride.

As parents our initial assessment was that it was not as cushioned along the back, seat, and arms as some car seats in higher price points, but my son likes it and says it is comfortable. Even with the lighter cushioning, the sturdy steel construction and substantial headrest put our minds at ease with regard to safety.

We all liked the multiple cup and snack holders on both the left and right side of the seat. One thing of note is that the cup holders are an 1/8" too small for his water bottle (diameter 3.9"), which can rotate freely in the cup holders, but is difficult for even an adult to remove.

I feel like this car seat fits my 3 year old better than some of the "all in one" car seats, which were already becoming tight on him even though he was within the specs. There is plenty of length in the harness to allow for him to easily get into the car seat.

I also like that the lever to release the harness is tucked away more so than some other car seats we have tried. My son quickly figured out how to get out of those other car seats. I feel confident that he will not be able to loosen this harness as easily.

I have noticed that tightening the harness straps requires a little more attention than previous car seats. More force is required to pull on the strap to tighten it. I am hopeful that this will loosen up some over time. Also, there have been a few occasions where my child is properly seated in the car seat before leaving, but upon arriving at our destination is looser than I would like to see. I think this may be a result of the car seat being more upright than those we have used in the past. I believe slack is being created because his back is not fully against the back of the car seat. This has been easy to remedy, but is worth noting for other customers.

Quality Convertible Booster Seat
August 12, 2019
The minute we received this Britax DualFit Harness-2-Booster seat in the mail, my 5 year old begged me to switch out her old convertible car seat for her "new ride". The latch system in my mid-size SUV has been difficult to access in the past with other car seat models, but this Britax booster was fairly simple to click into place. It feels very secure and sturdy, and my daughter absolutely loves it! She says it's comfortable and feels like a big girl, even though we will still be using the harness system a bit longer. I like the fact that it can accommodate a child up to 65 lb with the harness, and then up to 100 lbs as a booster seat. This will hopefully be the last seat we need to buy for her. The only issue now is purchasing another one so she doesn't whine about getting into the older model car seat in my husband's car... Thanks to the weeSpring Parent Panel for providing me with this harness high-back booster!

Super sturdy!
August 11, 2019
This booster feels really sturdy. The last booster we had didn't have the five-point harness, only seatbelt guides, and I feel so much better having my daughter in this one. She meets the height and weight requirements to be in a booster with seatbelt guides, but I love that this still has the harness option until I feel ready. The last booster we had was also barely padded at all and I always worried she was uncomfortable. This seat has much more cushion to it, which is nice. It was simple to adjust the seat to fit her height and super easy to install in our vehicle. My only complaint is that it is heavy. I received this seat as part of the weeSpring Parent Panel in exchange for my honest review. I am very pleased with the performance of this product.

Overall Great Seat
August 11, 2019
I was impressed with this seat. It has some weight to it making it feel very sturdy. Nice amount of cushion on the seat and the back. I love the no rethread harness! My almost 3 year old is on the small side for his age, weighing 27 pounds. He looked a little small in the seat when he sat in it but I still felt he was safe with the minimum weight requirement of 25 pounds. I wish the chest clip was a little easier for me to unclip but that's a minor drawback. All in all, a great seat. Thanks to the weeSpring Parent Panel for providing me with this harness high-back booster to try out.

Great car seat for a growing child
August 11, 2019
I received this car seat from the weeSpring Parent Panel and it came at just the right time. My almost three year old needed a larger car seat and this fit the bill. It was very easy to install and adjust the straps. My almost three year old loves that it has two cup holds just like his older brother's carseat. :) And I am happy he now has a car seat that will grow with him and can be used as a booster seat as he grows bigger and bigger.

Great seat!
August 11, 2019
I was given this harness high-back booster to try as part of the weeSpring Parent Panel. I tried it out with my tall 5 year old. He is very comfortable in this seat and loves the dual cupholders. I loved that there was no assembly required out of the box. This was my first time using a Britax seat, so I had to get used to the method of adjustment, but quickly figured it out. It is super easy to install! I only with the harnessed height limit was higher- my kiddo will quickly outgrow the harness setting of this seat. This seat is great for average-height kids! I will be holding onto this one for my younger son to move into when he is ready.

Great high back booster!
August 11, 2019
I was very excited to receive the Britax DualFit Harness-2-Booster. We have never had a Britax car seat and I was excited to see if this one held up to Britax's great reputation. The short answer is "yes it did!". We are using this in the high back booster mode with the seat belt for our 6 year old daughter who is 49" tall and roughly 50lbs, and it is installed in our Subaru Outback. Here are the pros and cons of this seat:
- easy install (Subaru seats recline so to get a tight install, I recline the seat and tighten the car seat in and then raise the seat back upright, which ALWAYS produces a tight car seat install)
- narrow seat (doesn't take up tons of the backseat and you might be able to fit 3 across)
- two cup holders and storage spaces (my kids always like to bring little toys or drinks and this helps keep those contained)
- not bulky and heavy
- has a steel frame
- booster mode works for up to 110lbs
- has different reclining options (so it can be used in harness mode with our 3 year-old too)
- fits our very tall 6 year-old and she is comfortable sitting in it
- good cushions on the seat
- seat covers are easily removable in sections for washing

- when not using the harnesses you are just supposed to tuck them away into the side wings of the car seat but they do not stay very well in there, it is a bit annoying
- The seat bottom lifts up to help with install but it is flimsy and cheap plastic compared to their other seats that have the Clicktight function

Overall, this seat works great for us and our car perfectly. I would recommend this harness and booster combo to friend and family if they were in the market for a cheaper Britax model. Thank you to WeeSpring Parent Panel for allowing us to test out this great car seat!

Comfortable, Sturdy & Safe
August 10, 2019
My four year old feels like such a big girl in her new car seat! I'm loving the structure of this seat as it is easy for her to climb in on her own and it's not as bulky as most other car seats. With baby #3 on the way we got this seat in perfect time to transition my girls seats and especially to be able to now fit 3 car seats in the same row. I feel like when I've looked at other narrow 2-in-1's they feel less sturdy which make me feel less safe. I love that this seat has the steel frame for impact stabilization and 2 layers of side protection that brings much relief to this momma. This seat feels sturdy, safe AND my girl says it is comfortable. That's a big deal as she has sensory issues and usually struggles with longer trips. We just made a 6 hour road trip and there were no complaints from her, WIN! This is our first Britax, so installation took a bit longer but we figured it out. I appreciate that we can keep her in the harness up to 65 lbs and use it up to 100 lbs, so hoping this will be her last seat needed. A minor detail that we also like is the cup holder. It's a great size and doesn't stick out in the way. Thank you so much to the weeSpring Parent Panel for providing me with this Britax DualFit Harness-2-booster!

Quality Dual Feature
August 10, 2019
I really like this DualFit Harness-2-booster. I was easily able to adjust the 5 pointer harness to fit my 4 year old, and was very quickly able to change it out to fit my 7 year old as a booster. He's very tall, so it's hard to find boosters that are quality and go high enough for him. This one still has plenty of room for growth. I was also shocked that I could fit this in the back of my sedan with 2 other carseats installed. The cupholders are a nice feature that we usually have to skip, as they add too much width. These cupholders are extremely streamlined. And of course, my son said it was a very comfortable seat. I did receive this product for free as a part of the weeSpring Parent Panel.

Great car seat!

I received this car seat as part of the weeSpring Parent Panel. My daughter is 2 years old and I had a different "grow with me" type car seat, but we love this one so much more. It seems to sit more upright and is much less bulky that the other one. It is easy to use and move from seat to seat as needed. The cup holders seem easier for my daughter to reach and because of the upright positioning she is less inclined to kick the back of my seat...unless she's throwing a fit :). Great seat and excited to use it as my little grows.

Great overall booster for the price
August 9, 2019
I received this booster as part of the Weespring Parent Panel. It is a good all around booster seat. I like the five point harness, but I would have liked longer and thicker pads on the shoulders like other Britax seats. I also miss the hugs pads on the chest. The pad on the buckle comes off easily or flips over the buckle, but my 5 year old is pretty good about fixing it himself. Installation was straightforward and similar to all of the other Britax seats I have installed. It only took about 10 minutes. The no re-thread adjustment of the straps is great and makes it so easy to size to the child. My son says it is comfortable and likes having two cup holders. His only complaint is that the cup holders are a little small for his water bottle. Great seat for the price point. We have only used it as a 5 point harness so far, but I anticipate using it as a belt positioner will be great too.

Versatility, safety and comfort all in one.
August 9, 2019
The Britax DualFit Harness-2-booster child safety seat is very versatile. I am a mom of 10 and have been using child safety seats for almost 30 years. This seat is easy to use and was relatively easy to install. The only seat I find easier to install is the Click-tight version of the same seat that we use in our other vehicle. I like that my 5 year old is able to secure herself independently and is also able to get out without assistance. It was easy to adjust the seat to fit my daughter and can easily be adjusted to fit my 7 year old son without uninstalling the seat. One of the best safety features of this seat is the ability to keep the kids in a harness longer. My only complaint is that the seat is a little wide, especially at the front, which makes fitting another seat next to it very difficult and also makes the back seat a little cramped for the other kids sitting there. I like that the cup holders are deep enough to hold cups in place. I would have to say the best thing about this seat is that my daughter likes it! She didn't like her last one because it was so hard to buckle and she says this one "feels nice." Thanks to the weeSpring Parent Panel for providing me with this harness high-back booster seat. Car trips are definitely better with kids that are comfortably strapped into a seat that will keep them safe.

Safe and secure!
August 8, 2019
I was looking to transition my 3-year-old into a narrower harness-to-booster seat like his older sister to fit more seats in the car, so I was so grateful to the weeSpring Parent Panel for providing me with this product! We love all things Britax and trust this brand to keep our kids safe, and this car seat does not disappoint. The no-rethread harness is great to adjust perfectly to my son's height (and as he grows), the belt buckle is easy enough to move outward (with a little help from the manual), my son thinks the seat is very comfortable as the seat can be reclined and is well-padded, and this will last him until he outgrows car seats and boosters altogether. Also, he now has his own cupholders! The best thing is that this car seat comes with the clickable lower connectors (not the cheapie hooks) that makes it easy to install and remove. I appreciated having the guide to install right on the seat so I didn't have to find the manual. The seat is a bit heavy for moving to and from different cars, but that just means it is more stable and sturdy. We love this car seat and my daughter now wants the same one.

Booster Love!
August 7, 2019
I received this harness high-back booster from the WeeSpring Parent Panel, and we LOVE it! The manual was easy to navigate through to learn proper installation for our vehicle. We used a seatbelt install which is always tricky with our van but with this seat I didn't even break a sweat! Easy install and fits great in the captains seat. Easy to adjust, comfortable to sit in (so my children say) and they love that it's open enough for them to see around the sides but also keeps them safe. Both my children wanted to try out the seat and it was easy to adjust the head rest and straps for each child's height needs, one child is 5 and 46 pounds and the other is 3 and 37 pounds. Buckling up is a cinch and has made school pick ups so much easier than our previous booster! We also love the dual cup holders on this seat, bonus! We would definitely recommend this seat to others.

We were gifted this car seat from weespring and britaxus a couple of weeks ago and it's been great!
Review by Connor (4 years old):
What do you like about your new car seat?
C: it has a food cup holder, that I can see the roads, and I can see the tops of the high high buildings.
What's different about your new car seat?
C: I can do the top AND bottom seat belt.

This car seat sits up a little higher than his previous chair, so he can see more out the windows. He was VERY excited the first time we went for a drive with his new seat.
The "food cup holder" he refers to is a second, rectangular cubby behind each cup holder on either side of his legs. He christened them food holders and puts any and all car snacks in those cubbies.
He can buckle himself, y'all. He's been able to do the top buckle for awhile, even with his old car seat, but he's never been able to do the bottom. Until now! He's not always successful with the bottom buckle, but when he is, it's like he won the lottery. He is also very happy with himself (and the new car seat) because he's able to UNbuckle himself every single time.

I like this car seat because it enables him to be more independent, it's very adjustable and it will most likely be the last car seat he'll ever need. It has two options: the 5 point harness for kids 25-65 lbs, and then it can be changed to a booster seat for kids over 45 lbs. Basically, it's gonna last forever.

Solid seat
August 7, 2019
I received the Britax Dualfit Harness-2-Booster seat to try for free from Weespring parent panel in exchange for my honest review. I have always used another specific brand for all the case seats I have for my two children, ages 2 and 5 but have heard amazing things about Britax so I was excited to try one of their seats. Upon receiving the car seat I was impressed with the packaging as it was very fitted to the car seat with no wasteful bulk. Once it was out of the box I noted how the seat had more padding than other seats I have owned. I also liked the placement of the cupholders and the storage space under the seat for the LATCH system strap when not in use; however, the plastic piece that covers the storage space is quite flimsy and I almost broke the plastic clips that hold it in. Since this piece does not impact the ability of the seat to keep my child safe I was not overly concerned. The head surround piece does impact safety and is rather insubstantial which did concern me slightly but the rest of the seat is extremely solid. I proceeded to install the seat into car using car the seat belt. The path that the belt is supposed to be in is easy to see therefore it is easy to see if the belt is in the right place or if it's twisted. I also find that it's easy to have the belt slip out of place while installing the seat which leaves the seat installed improperly and takes some messing around with it to ensure proper placement. Once installed my daughter couldn't wait to try it out and she loves it. The straps stay open after getting her out so it's easier to buckle her in and less likely for the straps to get twisted. I love that it will transition with her. Overall this seat is very solid, fairly easy to install, compact, and provides decent cushion for the child. I would definitely recommend this seat and am converted to a Britax lover!

Great slimmer designed car seat
August 7, 2019
Thank you WeeSpring Parent Panel for letting my daughter try out this car seat! My 3 year old is tall. we used it in my husband's car (small compact), it fit great. He doesn't have a lot of room in the backseat, so having something she could climb in and out of easily, was essential. It is a slimmer design than other bulky car seats. I love that this is a grow with her seat, so that we don't have to buy a new booster seat when she is done with the harness. The harness and height is very easy to adjust for my husband. I love that my husband could install this seat without my help.

Awesome seat!!
August 7, 2019
LOVE LOVE LOVE this seat. It was very easy to install in my suv. Nothing complicated about installing it, as long as you follow the directions in the manual. The directions in the manual are well laid out and I really like knowing how to safely install this seat. It's very easy to tighten and loosen the straps, as I do this every time my toddler gets in and out of it. It's very comfy, good padding. She has always hated the car and in this seat, she's very happy. She's calm and doesn't cry like she has in the past. I love that it has BIG cup holders because my toddler has various sizes of cups. I appreciate this is a great seat, that also grows with her and can be a high back booster when she gets big enough. Seats are expensive and it's tough to have to replace them as they grow. So I really appreciate a seat that can grow with them!! Overall this is a great seat and I love it, and so does my toddler! I feel like she is very safe in this seat and of course that's what all parents want! I received this product from the weeSpring Parent Panel.

Easy to use carseat
August 7, 2019
I was given this for review by WeeSpring Parent Panel. It fit both my girls very well. My 2 year old is 36lbs and still rear facing but will use this as soon as she turn forward. My 6 year old fit perfectly and was a big fan of how "comfy" the seat is. She uses it as a high back booster and I was very impressed with the shoulder strap fit. Out of the box it was really easy to adjust and install. And switching between the girls was a breeze! It is rather wide but that isn't a problem in our large car.

Great Carseat
August 7, 2019
The Britax dualfit harness 2 booster is a great carseat. I love that it has a 2 position recline to it. The seat is well padded with nice comfort pads for the straps. My son loves that it has arm rests and the double cup holders is real nice. It installs very easily and i had no trouble installing this seat. I like the lower anchors have storage inside under the seat. The buckle is very easy to move without removing the whole thing. Adjusting the height of it is very simple but you have to make sure it has enough slack so it stays where you put it. I would be sure to read the manual a few times so you can figure it out. This harness to booster system is great. Thanks to weespring parent panel i was able to review this for free for my honest opinion.

Upright, but still snooze friendly!
August 6, 2019
We have been searching for the right booster/harness combo seat for our three-year-old. We were so excited to receive the Britax Dualfit. Not only is it a great price point, but the quality is everything we would expect from Britax. Our favorite features are how easy the carseat is to install AND remove - since my husband and I trade out the carseat between cars, depending on who is picking up or running errands. No tangling of the seatbelt, the belt path is easy to access! We also like how quickly we can adjust the height and shoulder straps; our three-year-old recently went through a growth spurt - we didn't even have to remove the seat to adjust! Our toddler would say her favorite features are the upright seat positioning which allow her legs to dangle as they would in a regular seat (no legs angled into the seat in front of her or crunched to her chest), the integrated cupholders allow for secure eating on the go, and extra headrest padding makes this seat ideal for naps during long car rides or road trips. Thank you weeSpring parent panel for allowing us try out this carseat!

Good harnessed booster seat
February 25, 2019
I bought this seat for my soon to be 3 year old while her convertible seat will become my 1 year old's rear-facing seat. I used the latch installation and it took me a while with the user manual (first time Britax owner). This is a new seat on the market and video installation is not available yet (as of Feb 2019) but once a video guide is posted it would be very helpful for the owners.

Great carseat!
February 17, 2019
This carseat is just what I was looking for for my 4 year old. It's lightweight enough that I can transfer it between cars easily, but it is still a solid and well-made carseat so I'm not worried about safety. We will use it in the harness mode for a while before my son will be big enough to transfer to the booster mode. I'm happy I don't need to buy any more seats for him! The DualFit is perfect.

Exactly what I wanted
February 14, 2019
My twin boys just turned 4 and I wanted to switch them to a forward facing car seat that would last. The DualFit is definitely just that. It was so easy to fit to their size with the quick adjust harness and I couldn't believe just how easy it was to install into my vehicle. I love that I can keep them harnessed up to 65lbs and use it in the belt position up to 100lbs so I won't need to purchase another car seat for them again. There are so many safety features such as the steel frame for impact stabilization and 2 layers of side protection that I hope I never have to test but make me feel relief knowing they are there. They find it comfortable with the multiple recline positions and have been taking full advantage of the handy cupholders. I would highly recommend this to anyone whose child is ready for the forward facing stage.
