  • CLICKTIGHT® INSTALLATION: Install with confidence in 3 easy steps: Pinch to open, thread and buckle, click it closed!

Great Seat

I only use Britax due to the high rear facing limits and safety ratings. The installation takes some learning but easier when you get used to it. It's a heavy seat and not slim, so I wouldn't use it if I had multiple children or if I was taking a seat in and out. I only have one child and can invest in a seat like this. I would use Britax over and over again.

This is our second Britax One4Life, and it came with lots of extra padding that we hadn't had on the first one that we bought 1 year ago. The instructions for seat instal were simple enough, but instructions for what to do with all the padding to make it comfy for my new forward facing boy were vague and unhelpful. Overall, we love this seat. It has plenty of room for my long kids, and they seem to have no issues being in it for long car rides.

Perfect child seat 0-10 years

This review text is styled with strikethrough formatting

It's the perfect child car seat for newborn yo 10 years old, lots of safety measures in place to keep your child safe and comfortable when traveling in the vehicle unfortunately it arrived too late for me but would highly recommend,

About this review:Walmart fulfilled this order and the fulfillment issues were not the fault of the seller.
