Bottom line

The Evenflo Amp Belt-Positioning Booster is a basic backless booster that reviewers say is very easy to install and use. Kids like it for its big-person features, like cup holders and bright, fun fabrics. While the seat is more portable than a high-back booster, experts note that high backs offer more safety features. Additionally, the wide base may not fit well in narrow or contoured vehicle seats.


A best bet for belt fit. The Evenflo Amp Belt-Positioning Booster uses a vehicle's existing seat belts to secure a child. The seat receives solid marks in independent testing, but experts note that it doesn't offer the side-impact protection or more precise belt placement of a high-back booster. An included seat-belt clip helps ensure proper belt placement, though. The Insurance Institute for Highway Safety (IIHS) names the Amp a "best bet" for proper belt fit in almost any car. The Amp can become a projectile in a crash, so it should be belted to the seat even when it's unoccupied. It expires six years from its date of manufacture.

Ease of use

Easy to use, but has a wide base. Reviewers say it's hard to go wrong using the Evenflo Amp Belt-Positioning Booster. While most say they didn't need to use the belt clip for proper seat-belt placement, those who did said it was easy to secure. The seat receives a perfect score in ease-of-use ratings by the National Highway Traffic Safety Administration (NHTSA), which says labels and instructions are easy to understand. The belt clip is simple to use but requires two hands, testers note.

Lifestyle features

Cup holders are expandable. The Evenflo Amp Belt-Positioning Booster comes with two cup holders and padded armrests. The cup holders have elastic bands that can stretch to accommodate larger drinks. While most reviewers appreciate this, a few say they feel flimsy. The seat pad is machine washable, but reviewers say it's easy to wipe away most messes. One expert notes that the seat is wide, so it may not fit well in cars with narrow or very contoured seats. At 4 pounds, the seat is a good candidate for travel, reviewers say. Evenflo offers more than 20 bright colors and patterns. The seat is recommended for children from 40 to 110 pounds who are 40 to 57 inches tall.
