PLATINUM EVOLVE IMAGINATION is rated 4.5 out of 5 by 18.
Rated 2 out of 5 by from Head rest pushes my sons head to far forward The head rest sticks out too far which pushes his head forward and looks extremely uncomfortable. The seat doesn’t tilt back much at all either. Which doesn’t help with his head being pushes forward. My son is 4 years old and 40lbs and because it sits almost straight up and his head is pushed forward I am debating on sending it back. Not the right for us. The material is very well made and well padded.

Rated 5 out of 5 by from Dry comfortable We bought this for our sons first birthday without realizing that it wasn’t rear facing, luckily our 5 year old is still able to use it until our son gets older! Very easy to install and easy understand instructions too

Rated 5 out of 5 by from Favorite car seat We bought this car seat for our daughter when she was able to go front facing. We love how snug she fit in it. We have been able to use it for every stage and the car seat has held up perfectly.

Rated 5 out of 5 by from great booster seat I have been using this booster seat for my baby for awhile now. I love it so much it's nice and comfortable and he can sleep in it and not have to worry about anything. I also love the color of the seat it is beautiful!

Rated 5 out of 5 by from I absolutely love this carseat! After someone broke into my car and stole my kids' seats, I bought two of these. Not only do they have all of the safety features I look for, but this seat also has a chime that alerts you that the child is in the car (so you won't forget them) and if they open the safety harness. My oldest loves the seat and thinks it's super comfy. He also loves the chime. Totally recommend to anyone in the market for a great seat that evolves with your child!

Rated 4 out of 5 by from Great seat, missing material as pictured. The seat is great, easy to use, easy to install, and comfortable for the children. My only complaint is the lack of comfort/shoulder pads on the five point harness portion. They are in the picture but were not on either of the two car seats I ordered.

Rated 5 out of 5 by from Love this car seat! We love this car seat in my car! It looks nice and trendy. It was so much easier to install into my car then other car seats I’ve had in the past. There’s multiple selections of colors that are super cute. It was so hard to choose just one! Honestly I think the best thing about this car seat is that it’s a 3 in 1 so we don’t have to worry about buying another car seat until this one is no good anymore. Definitely our favorite car seat ever!!

When our younger two get to this stage. We will be purchasing 2 more! Thank you Evenflo for keeping all my kids safe in the car!
