Weight: 20-100 lbs.; 22 to 40 lbs. with harness, belt-positioning booster for 40 to 110 lbs.
IIHS rating: Best Bet.
NHTSA ease of use rating:
Booster mode: Three out of five stars.
Harness mode: Two out of five stars.
Pros: Affordable harnessed booster. Dual cup holders.
Cons: Basic LATCH attachments (hook-style). Dated design. Harness only works to 40 lbs.
Comments: The Evenflo Chase (sometimes referred to as the Chase LX), has a dated design and is showing its age. This seat earned just two out of five stars when used with the harness in a government ease of use evaluation—and since that is the key feature of this seat, we will not recommend it. The IIHS, on the other hand, gave this seat a Best Bet rating.
One key thing to remember about this seat: you can only use the five-point harness until 40 lbs. Most modern harnessed boosters work to 65 lbs. or higher.
Bottom line: there are better choices out there for a harnessed booster.
