## What reviewers say

**Clek Foonf Slim Convertible Car Seat** — Only one whitelisted tester, the Good Housekeeping Institute, covers this Clek Foonf, and its notes are hands-on-qualitative (a lab staffer's long-term family use) rather than lab-measured. GHI names it Best Premium, praising tank-like steel-and-magnesium durability and a narrow build that can line up three-across, while flagging its 38-lb heft, rethread harness, and long-ride comfort.
