Great car seat
I saw some reviews that the shoulder pads don’t come off, which would make them hard to clean, but I just received mine and the pads are Velcro (see photos), so it’s very easy to remove and clean them.Overall, I love this seat. It’s easy to install, comfortable, and includes an anti-rebound bar. We use it as our travel car seat (we have the Nuna Exec and the Clek Foonf as our daily beasts and those are great too, but way bulkier to travel with). We also have a Graco Extend2Fit that we’ve used for travel, but it doesn’t have an anti-rebound bar, so I consider this our best travel car seat so far.

Love it so far
I will say that installing this car seat at first was a bit difficult and confusing for me, but I watch Britax’s video tutorials on youtube which helped. Now that I’ve uninstalled and reinstalled it a few times, I find it very easy. I love the click tight under the seat, it works great. The car seat is so secure and doesn’t move an inch. I find the adjustments very easy to use as well. It is very cute, and fits decently in my compact sedan (Chevy Cruze). It seems pretty comfy too.I, thankfully, can’t actually attest to the safety of this car seat, but Britax is highly rated in that department from what I’ve read. And I did a lot of reading before making my purchase.Overall, I really do like this car seat and recommend it. First time installation was difficult, but once you figure it out it is much easier. 👍🏻

Perfect car seat
We love this car seat! Our other seat is a Nuna, and this is on par for quality and comfort. It doesnt take up much space and is absolutely the easiest baby to install. Great for travel because of the ease of install if you have a cart for transport through the airport… will travel with this over our lightweight travel seat any day!

Great narrow carseat
This is a wonderful car seat. We have tried several car seats over the past couple of years because we have a lot of young children, and this has been my absolute favorite for rear-facing. It has a narrow profile, making it possible for 3 across. I like the anti-rebound bar. Installation is so quick and easy. It is a good seat to put behind a tall driver or a passenger who wants leg room because it is not very tall like some other narrow car seats we have tried. The price is not bad, especially compared to some higher end car seats. Overall, this is an amazing car seat.

Comfy seat with easy install
My son loves this seat! It’s super high quality with a nice amount of padding. The install is a breeze with clicktight and it was very easy to adjust to the correct settings. We haven’t had to wash the cover yet which will be the final test.

Fits Tesla Model 3 great
I was nervous about finding a car seat to fit in my back seat. The quality is phenomenal and my boy loves it. We haven’t used the cup holders yet but a great option. Super easy to install. I was hesitant due to the price of this one vs cheaper all-in-one seats. It is definitely a luxury car seat and worth the extra money.

We love britax for the comfort and safety !
Great things about this carseat its comfortable and has good safety ratings and comes in a range of colors! The downsides are its Heavy not easy to move between cars and deep cleaning is a bit of a chore.

The sturdiest car seat I ever did see…
Great option for our son who was showing signs of being increasingly uncomfortable in his infant car seat as he grew. Now, our son kicks his little feet all the way—no more crying during car rides! Most importantly, it’s sturdy! My husband and I tried to wiggle it at it’s base after tightening and couldn’t. When installed correctly, it’s definitely the safest place in the car.Buy the car seat.
