Evenflo RightFit booster seatBooster type: High back booster

Weight: 30 to 110 lbs.; 38″-57″ in height. At least four years of age.

Price: $56 to $90.

IIHS rating: Best Bet.

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

Pros: Affordable, multiple seat and headrest adjustments. Side impact protection.

Cons: Top harness height of 19″ means taller kids may outgrow the seat too soon. Pricey.

Comments: The Evenflo RightFit booster seat features some nice refinements over Evenflo’s other booster seats. The headline here is adjustability: the back rest has four adjustments. When combined with three headrest adjustments, you have 12 possible positions. Most high back boosters under $100 only have a few adjustments or none at all.

The RightFit also has Evenflo’s e3 side impact protection and activity lights (four LED lights on each side wing). Like most Evenflo boosters, the RightFit converts to a backless booster for older kiddos. Two built-in cup holders on the arms are well designed.

The negatives: the top belt height is only 19″—this is much shorter than the Britax Parkway (21.5″) or Recaro’s ProBooster (21″). Hence it may not the right booster if you have a tall toddler, as they may grow out of the seat too soon. We also found this seat’s $90 price tag a bit high, since you can buy a comparable Graco TurboBooster for $43 (although some colors are near $50).

Parent feedback on the RightFit has been mixed, with several folks criticizing the narrow shoulder belt guide (making it difficult to slide a seat belt through). Others complain the foam in the headrest breaks easily. Given some of these reviews, we’ve downgraded the rating. If you get this seat, make sure you keep the receipt so you can return it if the shoulder belt guide turns out to be an issue in your vehicle.

Rating: B-
