Recommended Use

  • Forward-Facing Harness: 22-65 lb, up to 49"
  • Highback Booster: 40-100 lb, 38-57", at least 4 years old
  • Backless Booster: 40-100 lb, 43-57", at least 4 years old

STOP using this child restraint and throw it away 7 years after the date of manufacture.

When forward-facing, children should use the built-in harness system for as long as possible until they reach the maximum forward-facing weight or height for their car seat. At that point, children should ride in a belt-positioning booster seat. A booster is no longer needed once the vehicle seat belt fits properly, typically when they reach 4 feet 9 inches tall and are between ages 8-12. Be sure to check your local and state laws, as well as AAP and NHTSA recommendations, for car seat usage.*

Difficult to install tightly
May 14, 2022
I chose this car seat because I wanted something that we could use for years, and which had a lock-off feature for installation. In spite of the Snuglock feature, I found it impossible to get a good fit with the seat belt in 5-point harness mode. No matter how tight I made it, with a little pulling, I could get the seat to slide all over the place. I got a slightly tighter fit with the latch belt instead, but still not the best. This was in a Honda HRV, so maybe it would install better in a different car.

Nice idea (converts to booster), but not great in practice.
