The best carseats I purchased!

I don’t know why I waited for so long to purchase this carseat for my twins. Maybe because some reviews I read, it cannot be tightened and knowing I have 2006 Toyota tacoma truck. Guess what? it was an easy installation and way better than I had. My twins loved it already. It’s very lightweight and properly secured in the car. It checks the box ✅lightweight ✅ slimmer ✅affordable ✅easy to install ✅easy to wash/clean ✅perfect size for my twins ✅ love the color especially the purple/black for my twins girl.

Don’t waste your money

I got my daughter the purple one about a year ago and I love it so I bought my son the same one in black. They’re very easy to install and easy to take apart to clean. I love that it’s the last car seat/booster I should need to buy. They’re also very lightweight and easy to move around. My kids find it comfortable and often fall asleep in it.

Excellent next step

[This review was collected as part of a promotion.] My daughter (almost 4) had outgrown her convertible car seat (not in height or weight, but in maturity and interest in sitting like the adults). This is the perfect next step to help her feel like a big kid, but still have all the safety protections she needs. This will be all she needs until she's a big kid and can sit on her own in the car.
