Weíve really liked this car seat for our 6 year old. I love that I can still have her in a 5 point harness bc sheís small, but that I wonít need to buy a booster when sheís ready for that.

We were recently in a major MVA (In a jeep grand cherokee, not salvageable) and both of my girls (2 and 3) came out with minor abrasions and bruises (and nightmares, but carseats can't help with that!) My oldest was in this model on the side of impact, and my littlest was on the opposite side in a forward facing boulevard model. For the amount of damage done to the Jeep, the fact that the girls are in such good shape is a testament to the safety features of these seats. Ease of installation is also paramount. Since the seats can't be used after the crash, I ordered two of this model from my bed in the Emergency Room, as my 2 year old is big enough for the Grow With You now. Of course any seat has little things we can gripe about, but in the end, SAFETY IS ALL THAT MATTERS.

This is a great seat. My online complaint was that my daughter has difficulty accessing the cup holders because her legs rest over the top of them a bit. I will say she is 7. I got this seat for her with the intention of giving it to my younger child soon when he turns forward facing and I will move her to a high back booster. This has plenty of room other wise for an older child! 48 inches 52 pounds. Love the clicktight function!

We purchased this for our little girl as we were upgrading her from her boulevard seat. The click-tight made it super easy to install and we love that sheís still in a 5 point harness. The fabric is really nice and easy to wipe clean. She absolutely loves the color and loves the fact that she has holders for her snacks and drink.

My 4 year old is very comfortable and i feel better knowing shes still in a 5 point harness. Highly recommend.

Not enough leg support on the seat for growth, adjustable back, cup holders but shallow, washable liner.

By Katie

Obviously, it sits a little straighter than the Marathons bc it is a different style but it was an easy transition for our 3-year-old. Very Very sturdy just like you would expect in a Britax. Not for a little car for sure. We put ours in our 3/4 ton truck and there is still plenty of room for the back console to flip down.
  • Large and roomy
  • Sturdy
  • Cute Print
  • Very good material and washes up nicely.
Best Uses
  • Large SUV or Truck
  • Takes up more than average space for a booster.
  • Prob hard to figure out at first if you have never used a Britax

Very easy to install and my daughter loves it! This is a great seat for her being in between a convertible (had to be passed down) but just a bit young to go into a booster. Would definitely buy again for another child.
it's OK, but not as easy to use as I'd hoped

This seat is safe, this seat is easy to install, this seat has washable fabrics. Why do I want to replace it with a different brand? Because my kids like my to loosen it all the way so they can buckle themselves in but then it's a pain to tighten the straps up again from super slack to super snug without snagging anyone's hair. It shouldn't be this hard!
  • -easiest seat ever to install with the click tight system
  • -adjustable recline
  • -easy to adjust as kiddo grows
  • -lots of clearance for big noggins to be protected by the seat
  • -comfy seat
  • -tallest child accommodations of HBB seat that I've been able to find for my tiny giants
  • -REALLY FRUSTRATING to tighten the harness straps! the shoulder harnesses pads keep getting sucked backwards into the belt path as I tighten them so I have to yoink them forward (potentially pulling my kiddo's hair) a few times every time
  • -creaky headrest if you didn't adjust the height juuuuuuuust right (really annoying if you're using the same seat for multiple kids and switching it often)
  • -the little clips that hold the seat pads on pop off all the time at the base/front of the seat frequently

So I have this car seat plus the britax grow with me CLICKTIGHT. I love the way they both work. I love that my bigger kids can still have the safety and security of a 5 point harness. They canít lean over to play with each other and slip out of the seatbelt the way they could if just using an adult seatbelt on a booster. That being said one day when they outgrow the harness limits this seat CAN be used as a booster with an adult seatbelt so I donít need to buy another. The only thing I will add is that I prefer the clicktight. Itís so easy to get in and out of my car or to reinstall it in a different row. The additional price for that upgrade is worth it. Oh also my kids love the double cup/snack holders. I do too Bc they still canít reach the door upholders when harnessed so this is helpful on road trips. And they donít complain theyíre uncomfortable on road trips (not til the end of the day). They can recline just enough that when they fall asleep on trips their heads stay back and arenít flopping around. My kids are now 5 and 7 yo. Weíve had these car seats for probably 2 years now. No complaints.
  • Ease to install
Best Uses
  • Older kids and bigger kids.
  • A little wide. Can fit 2 in the back of any car fine but def not going to get 3 in a row.

This seat is the highest harnessing seat on the market. You can install with the seatbelt in less than 1 minute with zero effort using the clicktight system. My favorite combination seat!
  • Easy installation. Comfortable. cup holders High quality.
Best Uses
  • Kids that are bigger but not ready for just a booster seat yet.
  • Only goes to 49? tall for a child in harness mode. But unless your child is very tall, they will fit for a long time

This is by far the easiest car seat I have ever installed! It took my husband and I 10 minutes, tops. And it doesn't budge! It's perfect for our extremely tall 3-year-old. And we love that, with the booster conversion, it will likely be the last car seat she needs. Do not hesitate. This is an exceptional car seat.

We love Britax car seats and this one is no exception. The Click Tight technology is outstanding - makes removal and install so unbelievably easy. My 4-year old daughter loves the color and how easy it is for her to get in and buckle herself in (although still safe enough that she cannot unbuckle herself without assistance!). The seat is heavy, yes, but that is due to the safety engineering and steel-reinforced frame. The seat fits well in the second row of my SUV and is rather narrow for it's class of seat. The no-rethread harness is an awesome feature and the seat also has dual cupholders and little snack/toy wells beneath each arm rest. The cover is very easy to remove and clean in the washing machine. The seat definitely sits more upright and makes my daughter feel like a "big girl" who can see everything as we drive. I love that this is the last seat she will need as it will transition into a belt positioning booster and grow with her. My only real complaint about this seat is that the cover tabs that secure it to the bottom of the seat are flimsy and constantly popping out, they are tedious to reattach.

By Tessa

This carseat is very sold and safe with the steel frames, but that means it is very heavy. It is not a carseat you want to move between cars or take to the airport.
Super comfy and my daughter loves it.
My only issue (and this is completely my fault) but I thought it was one where you could take the high back portion off and just use the seat as kids get bigger but you can't.
  • Safe
  • Easy to Clean
  • Comfortable
  • Easy to click in
  • Heavy
  • Back doesn't remove from the base.

Makes it easy to get my toddler in and out, easy to secure 5 point harness, smooth and easy operation and easy and rest assured install provides confidence and peace of mind. My daughter loves it, sits more comfortable than ever and I know sheís as safe as safe gets. Great product, worth every penny.

Britax’s New Version of the Frontier
By Tosha

on May 14, 2021

We purchased this a for our third booster harness seat for our daughter. She has the pinnacle in our other two cars, but she wanted a pop of color. It worked out nicely as it went into a smaller car. This model has one less layer, making it slightly thinner. The seat is still worthy of the Britax name and I fully feel she is safe riding in this seat. The instal was not as easy for me compared to installing the pinnacle. Iím not sure, but feel like the slight weight difference (this one being lighter than the pinnacle) played a part. I was able to properly and securely install it on the third try though. Overall, I recommend this seat second to the pinnacle based on my setup. If I had a car, opposed to an SUV, or had to get more than two seats across the back bench, I would prefer this model as it is slimmer in overall width.

We are a (mostly) Britax family and I love this seat. I ordered two for my older son ó one for each car. My husband has complained the headrest makes a squeaking noise when my son isn't in it, but I only noticed it once in my car, when it was frigid outside. Sometimes the Cliktight mechanism gets a little stuck if I'm taking the seat in or putting it out, but I just have to put a little extra effort into it and it's fine. My son loves it, especially the dual cup/toy holders.
  • Easy to install.
  • Dual cup/toy holders.
  • Looks great.
  • Headrest can squeak a little when the seat is empty.
  • Clicktight mechanism sticks a bit.

Sturdy seat not meant for portability
By Hal

on April 15, 2021

This seat, with the steel frame, is well built but heavy. The instructions as to how and where to use the harnesses is not the clearest, and using the car's belt system can take a few tries to get the tension correct (forward facing, at least). Once it's in place, it's secure though. If you plan to move the seat from vehicle to vehicle, it may be a little troublesome to go through repeatedly.

I recently purchased this seat for my 4 year old. It was an upgrade from his britax car seat that he just barely fit in. He loves the cup holders & cubby holes for his toys & he has room to maneuver again. I did a lot of research into car seat brands when I was pregnant and Britax was absolutely my favorite. That has been confirmed & reaffirmed continually over the years. Safety is outstanding. The ability to easily pull off the cover & toss it in the washer has been an absolute lifesaver (ever had a toddler projectile vomit in the car??) ! I HIGHLY recommend this seat!

Just received my Harness-to-Booster seat, and it was VERY easy for me (grandma) to figure out and install. It came in a cool carseat-shaped box (genius), packaging was excellent. My cat likes it for a playhouse now. Surprised my 5 yo grandson with it today, and he absolutely loves it, said it's really comfortable. I'm looking forward to a few good years of use of this well-constructed product.

I have been purchasing britax car seats for 6 years now, they were my go to brand. I recently upgraded my twins to the grow with me boosters. I haven't even installed them in the car yet and I noticed a piece was broken. The process to adjust the crotch buckle is poorly planned out. You have to unclip very flimsy, very cheap plastic clips that are holding the fabric on the seat. One of those clips snapped when removing, using the exact instructions in the manual. Why would you choose to use such a cheap design in an excellent rated, and one of the more expensive car seat options out there??
