AMP Backless Booster Car Seat is rated 4.0 out of 5 by 8.
Rated 4 out of 5 by from Great booster for the $! It’s a great booster for the $. I gave 4 stars instead of 5 because it’s very flat on the bottom. So, if you have an incline or curve to your seat, it can fit a little awkwardly in your vehicle. Works great in our minivan but not in the Cadillac.

Rated 5 out of 5 by from Love this booster! I have one for all my kids. I love how much room this booster has for the kids to get the seatbelt under the armrest. The booster is a nice size and I’ve taught my kids to lock the seatbelt shoulder strap when they buckle so I have peace of mind with them in these boosters. They are sturdy, comfortable, user friendly, easy to switch into other vehicles and easy to clean. I originally got one for my daughter and loved it so much that I got one for each of my boys. The cup holders are great too. There’s on each side. They don’t take up any addition space and don’t collect dirt/trash. I love these boosters!

Rated 5 out of 5 by from Wider seat, along with cup holders The booster seat is perfect for my granddaughter. My younger granddaughter is now a little jealous and would like one for herself. I was a little shocked when I went to buy the second one that it was double the price of the first. I called and was told it was a special discounted price. It is a very comfortable booster seat and my granddaughter feels like a big girl. Thank you for such a great product. Bill

Rated 1 out of 5 by from Worst Customer service!!! I bought the AMP booster because I mistakingly thought it was the bottom-only part of the high back booster that I currently have since it holds the same name AMP. I have the evenflo AMP high back booster (the seat part is detachable) and the bottom got damaged so I need to replace the seat part only. Anyway, this isn't compatible and I needed to return it. I contacted customer service and was told I had to pay for shipping both ways since it was my mistake or I could give the item to a friend. I will not be purchasing anymore Evenflo products!!!

Rated 4 out of 5 by from Love the Peace & Love and so did the children I ordered them because they were smaller than many others and we are having trouble buckling at the back 3 seats in the van. It helps that there are no protruding drink holder but they are still difficult to buckle for the children. There is not enough room for their hands to buckle when pushed all the way back - so we wiggle and take turns with buckling.

Rated 5 out of 5 by from Awesome I brought this today as a replacement for my old grow with me evenflo carseat. We got a good 4 years out of it. The cushion stop saying and my daughter always had a hard time getting to the cup holders. This carseat is a godsend. It looks easy to clean. The cushion is super soft. Also the cup holders should make it easier for my daughter to get to. I'm ecstatic.

Rated 5 out of 5 by from Great for bigger kids Just bought this booster for my son who is 4'5 and weighs 82 pounds. He is 6 and much bigger and taller for his age. All booster seats seem to be made for smaller sized kids but this one is amazing. It has a wider width which is much more comfortable for him. The cup holders are an added bonus!

Rated 3 out of 5 by from Just wish the car seat was smaller in width. In a small car, if you have three kids across the back. These seats are too big. I would love to see a 13" wide car seat so my kids can get to the seat belts which end up under the car seat and the seats are squeezed together side by side. They are constantly fighting to get their seat belts on. I'd recommend this product for a full size truck, but not a small car.
