The Clek Oobr is a bit of a splurge, but owners say it’s worth it, especially with its long, nine-year expiration date. Rigid LATCH connectors and a magnesium frame are notable safety factors, and parents love the nearly indestructible Crypton fabric. It also reclines for naps, a feature parents and kids both appreciate.

Parents looking for a basic backless booster will want to check out the Evenflo Amp Belt-Positioning Booster. Reviewers say it offers good belt placement and is easy to use and clean. The convenient cup holders expand to accommodate big water bottles, and the seat comes in a wide range of vibrant colors, appealing to kids who may balk at a booster.
