## What reviewers say

**Chicco KeyFit 35 Infant Car Seat** — One whitelisted hands-on tester (Reviewed/USA Today) reviewed this exact model, recommending the KeyFit 35 as an easy-to-install, comfortable, washable, budget-friendly infant seat while flagging it as bulky/awkward to carry and unattractive. No lab-measured data exists: Reviewed explicitly states it does not crash-test and relies on NHTSA safety ratings. (1 sourced review.)

**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. (1 sourced review.)
