PLATINUM EVOLVE THEO is rated 4.1 out of 5 by 7.
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 Awesome seat Love the seat the only thing I would change is make the straps easy adjust like the ALL in one seats.

Rated 1 out of 5 by from Not as described!!!! This was bought as my son's 2nd seat for my bf car, his 1st being a Graco 4Ever. We love the Graco, but thought the temperature regulating feature would be awesome for out little hot body baby (Plus they were a little on the pricey side at the time). NOPE....I was wrong! Every time we put him in there he starts fussing for multiple reasons.... 1. The seat is extra bulky, which is a contradiction in itself. 2. The recline feature is not really setup for forward facing, so his head continues to slouch down when he goes to sleep. 3. I understand the sides come out a little further for safety, but not only can he not see outside or interact with his brother, but he cannot feel the air if we crack with windows. Which leads me to #3. when we take him out of the seat he is soaking wet from not only being hot but working himself up in a tizzy because he do not like being hot AT ALL. I usually do not write reviews, but these things are just to expensive for misleading information. We'll be looking into another Graco 4Ever. You get what you pay for.

Rated 5 out of 5 by from Innovative and Easy to Use The Evenflow Platinum Evolve car seat was easy to install which is always a plus for an on-the-go family, but the best feature by far is the innovative Outlast Performance Fabric! In the past, my 3 year old has always complained about her back getting sweaty in other seats, but not in this one!

Rated 4 out of 5 by from Parent Approved - Child Likes It We are very happy with this car seat! It was easy to install and we feel like it is extremely secure. Unlike some other car seats we have had the straps adjust/tighten evenly and easily. We have had some major issues with one side tightening more than the other with some other brands. Our girl seems very comfortable and sometimes protests when it is time to get out of the car! This has never happened before! I was concerned that it was going to be a bit uncomfortable for her to sleep in but she has had no problems (we drive a lot) but her head does bob forward a lot. (Thinking about getting her some type of pillow to help with that.) My only complaint would be that it isn't really snack friendly. Like I said, we spend a lot of time in the car resulting in a lot of snacking in the car and snacks easily get caught in the crevices. A small price to pay for such a great car seat. We were using the Chicco brand previously and I find the Evenflo-Platinum far more superior!
