Platinum Evolve 3-in-1 Combination Booster Car Seat (Dreamer) is rated 4.4 out of 5 by 40.
Rated 5 out of 5 by from Easy Transitions! This car seat offers 3 stages for your growing child and it is SUPER easy to make the transitions between the stages of the car seat! My favorite thing about this car seat is that it is narrower than similar seats. If you have 2 children in car seats, it makes it easier for you to sit in between them in the back seat. Or, this seat makes it possible to fit 3 car seats across your back row as well. I also like the fact that the safety features and the style of the seat are going to stand the test of time if I want to use it for another child in the future.

Rated 5 out of 5 by from Great seats! I have twin 3 year old girls and finding car seats they both love and are comfortable in is hard. I have had these car seats for a month and love them!!!! I love the head rest that makes it more comfortable for my girls to sleep. I love the double cup holders for drinks and snacks! I also love the fact that this is the last seat I will have to buy for them since it is 3 seats in one!! The fabric is great for clean up too and I have a lot of clean up with twins!!! Overall great seats and would recommend!!

Rated 5 out of 5 by from Nice and Comfy!! This is a great car seat!!! The fabric is extremely comfortable and provides good support. Harness strap pads help protect her neck from the edges of the belt. The seat isn't too wide to allow too much wiggle room but the cushioning is soft and flexible enough to not be too snug. The recline feature gives just enough tilt to be comfortable and not let her head fall too far forward when she falls asleep. I love the little flaps to hold the buckle so you don't have to search for it everytime when it falls down into the side of the seat. The 2 cupholders positioned in a reachable distance when the harness strap is on is definitely a bonus feature!! It is great to have the long term option of using either the back or backless booster. Only things I wish were a little different would be that the harness straps adjusted with the headrest and that the headrest wasn't quite so long on the wings because it blocks her vision from looking out the window. I use the seatbelt for installation so the standard latch hooks aren't a big deal.

Rated 5 out of 5 by from Well made and easy to use!! Great, high quality and well made seat! I love the 3-in-1 feature of this seat and how easy it turns into a no back booster seat! The head protection gives me peace of mind. I really like the fabric and how breathable it is in the summer as well as the warmth it provides in the colder months.

Rated 3 out of 5 by from Too tight! I bought this seat for my tiny 4yo about a year ago. It was great at first. Easy to install, comfortable fabric, lots of padding, and it seems very safe. The only thing she complained about were the MASSIVE headwings (She can't see around them.). Recently, though, she's begun to complain that she feels "squished" in the seat. I looked at the fit, and her shoulders are pressing against the sides of it. In addition, the harness straps are cutting into her neck. My daughter is now five years old. She weighs 30 pounds and is 37" tall. There is absolutely no reason for this seat to NOT fit her, but it most definitely doesn't. Considering that the seat is causing discomfort in a child of her petite size, I can't imagine using it for a child of average height and weight. She's far too light to use it as a booster seat, so I'm basically out $150, because now, I'm going to have to buy something that fits her correctly. Very disappointed.

Rated 1 out of 5 by from Manufacturer website incorrectly lists LATCH type Manufacturer website says this product has "SureSafe™ Installation" (meaning the push button LATCH mechanism). http://www.evenflo.com/Products/Comparison/?ids=5435,5090 This product does not in fact have the "SureSafe" LATCH. Only discovered that it has the standard LATCH components after I purchased the product and opened the box at home.

Rated 4 out of 5 by from Great Design I recieved this seat just over a month ago for my 2 1/2 year old to replace an old Graco seat. So far we both love it. He loves how comfortable the seat is and the fact that now he has 2 cup holders to load up with drinks and toys. I like the head support and the ease of installation. I do have issues with the bottom buckle being difficult to latch sometimes but other than that its a great seat.

Rated 5 out of 5 by from Love the idea that parents can by a carseat that will adapt to the growing child! Evenflo thought of everything with this seat. They not only focus of safety, but the small details that really make a difference. For example, the outlast fabric that help keep children comfortable during the cold and warm temperature is perfect. My favorite feature is the buckle pockets! Genius!
