Britax Grow with You ClickTight Harness-2-Booster Car Seat, 2-in-1 High Back Booster, Black Contour

I can't say enough good things about this seat! I was really stressed about finding the best and safest seat to transition from the Nuna Rava that we've been using for the past 4 years. We've used Nuna seats since she was born and assumed we'd go with them for a high back booster as well. After reading reviews regarding the comfort level and checking the specs, we decided that we were not completely sold on their booster, especially at the price point. So I started researching other options. A big factor, along with the safety rating and comfort level was having fabric that wasn't treated with harmful chemicals, which is a hard find. Enter this gem of a car seat from Britax. First, I love that it has a 5 point harness! My child is 9 but very petite and we all were a bit nervous about using the car's shoulder belt until she got a little bigger. The five point harness fits perfectly and "it's so comfy I don't even feel it there!" Score! She also loves how comfortable and roomy the seat feels and that it has 2 cup holders that her cups actually fit into. She also said that the armrest level was "perfect" since a lot of the other armrests were really low. This is not a lightweight seat. It weighs about 25-26 pounds. However, it is STOUT! It's got plenty of protection from side impacts and it just feels so sturdy and insulated, I know that, God forbid, if we were to be involved in an accident, she would be well protected, which is a weight off my mind. Added bonus is the install is ridiculously easy! I've never been able to install a car seat for some reason, so that task fell on the hubby. I got this baby installed in like 5 minutes and when I did a shake test to make sure the seat was secure, the car shook, but the seat did not budge, thanks to a secure fit using the car's seat belt and the back tether. There are so many other little things to love about this seat, it's hard to name them all without making this review even longer but suffice to say, I'd recommend this seat to anyone looking for an amazingly safe and comfortable seat without the nasty chemicals. Thanks for keeping my baby safe, Britax!

This fits our 2019 Explorer exceptionally well. Both kids are comfortable in their Big Kid seats.I like how the straps never tangle, and buckle is easy to reach, the head support is comfortable and safe. We love how easy the installation is. The cup holders are the right size for the little trinkets three year olds kids pack around with them.The safety is top of the line. Worth the cost.

First of all, the height limits on this seat are incorrectly advertised. Britax has published that this seat has a maximum standing height of 49” for harness mode, however they also state that it has a maximum seated height of 20.5” for harness mode. For clarification on why these two heights don’t match up: the other Britax seats that are known to have a max seated height of 20.5” also have a max standing height of 58”. So obviously if this seat has a max seated height of 20.5” (which it truly does), by default the standing height must be higher. I have contacted Britax about this but they are unwilling to admit the error, which is a shame because most people who are looking for a harness to booster seat with a higher height limit (like we were) are going to pass over this seat based on the incorrectly published standing height limit, and not dig deeper to realize that the seated height limit is actually quite high.So to recap: this seat has a 20.5” seated height limit for harness mode, which is equivalent to a 56”-58” standing height limit, and is therefore an excellent option for people who wish to keep their older (or just taller) kids in a harness for longer.Our 5.5 year old is 46” tall, but has a long torso and has outgrown her excellent Britax Boulevard car seat, which has an 18.5” seated height limit and a 49” standing height limit. I’ve played around with the harness height on this new Grow With You seat, and it still has several more inches to go up in harness mode from where it fits her now, which means we will be able to keep her in a harness for a good while longer before we need to convert to booster mode.This seat seems comfortable from what I can tell (and from what my daughter tells me). It has a nice wide seat and it is roomy in her shoulders (unlike the Chicco MyFit we tried out which had a shockingly narrow seat and not much shoulder room width-wise), and I have no doubt that this seat has enough room for her to grow over the next 5+ years that we will need it.As always the Britax ClickTight feature is a game changer for quick, easy, and correct installation. Something to note however, is that the base of this seat is different from the Boulevard and Marathon seats, meaning the ClickTight feature on this seat is also different. Although we have owned a Britax Boulevard ClickTight seat for the past 5 years, I did not intuitively know how to use the Grow With You ClickTight, and I did need to read the instruction manual. However, once I read the manual it was a piece of cake and I was able to securely install the seat in minutes.Also, I’ve read that there were issues with tightening the harness straps on the Frontier and Pinnacle seats. This Grow With You seat does not have any of those issues; it tightens and loosens easily and securely.And of course, the color choices on this seat are quite nice, and my daughter LOVES her purple seat. My only complaint is that the fabric is not machine washable with this model. That should be a standard feature on EVERY car seat, and I do find that really irritating. But overall this is an excellent seat, as I have come to expect from Britax.I’ve attached a picture comparing our old Boulevard seat (left) at its highest harness setting, with our new Grow With You seat (right) at one of its middle harness settings.

This is a great car seat.Really easy to use and set up.

We absolutely love this seat. We actually have three of them! Lightweight, easy to install and easy to transfer to other vehicles if needed quickly. Comfortable and safe!

​I was reviewing several car seats before deciding to buy this one. Despite the fact that in the car seat rankings and several reviews from other buyers mentioned that the headrest was very noisy and looked flimsy, I decided to take a chance. So far, I've been pleasantly surprised, as my headrest has been strong and quiet. I think this might be because I read the instruction manual and made sure to install the seat correctly. It's very important to place the rear belt in a "V" shape behind the seat. It's a sturdy chair with a reinforced aluminum frame.​The only detail I have to point out is that the clips that adjust the seat liner come undone easily. Even though the fabric hasn't moved out of place so far, it's just a matter of putting them back in. Also, it's a very spacious seat, where the child fits comfortably and the fabric is easy to clean. Despite those small details, I am very happy with the purchase and would recommend this seat, but with the warning to read the installation manual very carefully. I am still in the process of testing the seat, so I will update my review if there are any changes or unstable performance.
