Britax One4life Slim All in one car seat.
This seat is comfortable and has many features that make it a great seat. It is a little heavier than the car seats found at discount stores but this makes it a more solid product.

Britax for the win!
This car seat is the perfect size for our Tesla model y. It needs to be in a side seat for the anchors to properly work. It’s great for traveling because of how thick the padding is and how comfortable it keeps my kiddo. The buckles are easy enough for her to do herself and the cup holders are everyone’s favorite.

Britax is a favorite once again
Color as expected, easy to install, slightly heavy but we bought two so we won’t need to switch from one car to another anyway

Box arrived completely open
I like the car seat and baby won’t be here until February to try it out however, the box arrived completely open with all the tape cut on it. It wasn’t one piece of tape, it was every single piece on the box. Some of the plastic covering had been cut as well. The actual seat looks fine it just makes me uneasy that it was completely open upon delivery.

The belt to tighten is hard to pull!

Customers beware of Sub-par Britax Customer Service
Beware customers of Britax. Worse customer service experience that I have experienced. Am wondering how a supposedly "professional" company is willing to operate with such bad customer service and contact information. I attempted to contact the Britax customer service via their telephone number advertised in their web site, i.e., BOB, who replied with a message "we are currently on vacation". Well, thank you for informing me of your vacation plans, BOB, but who know when you will be returning and if you will answer my calls and messages? As prompted by the Britax answering machine to "leave a message", but I was transferred to a non-existing and non-responsive number. If you are purchasing a Britax children car seat, then do not expect customer service assistance, let alone anything responsive" customer service. A real disappointment: I now regret my purchase of (expensive) Britax car seats.
