Weight: 30 to 100 lbs.

Price: $30 to $40

IIHS rating:
Amp High Back: Check Fit.
Amp High Backless: Best bet.

NHTSA ease of use rating: Five out of five stars.

Pros: Affordable. Deeper side wings for more side impact protection. Comfort touch padding.

Cons: Lack of seat padding. Feels cheaper/flimsy compared to other similar boosters in same price range.

Comments: The Evenflo Amp High Back Booster is similar to the company’s Big Kid with a couple of differences: the Amp has a bigger headrest for more side impact protection. And the Amp has two integrated cup holders (the Big Kid’s cup holders can retract into the base). Price-wise, they are about the same. Both seats convert into backless boosters for older children.

As with Evenflo’s other Amp seats, the emphasis here is on bright, neon color accents. And just to confuse you, there is also a backless Amp booster ($20 to $35).

Parent feedback on this seat has been positive, although quite a few note the lack of seat padding—we’d say the padding is on par for seats that cost $35. Meanwhile, Consumer Reports gave the Amp high back its highest rating, earning an “excellent” for crash protection.

Between the Graco TurboBooster and this seat, we’d give the TurboBooster a slight edge in overall quality and fit to child. “Flimsy, cheaply built” is a common refrain from those parents who are unhappy with this seat. . .  . despite the rave reviews from Consumer Reports.
