Buckle up! Malin Akerman and Beverley Mitchell keep their precious cargo safe in Clek Foonf car seats. And TheBabyGuyNYC Jamie Grayson believes the seats are worth their price tag ($450, clekinc.com).

“Aside from the fact that the Foonf isn’t hideous … it has the highest rear-facing weight limit in the American industry, at 50 pounds,” Grayson, a gear expert, tells Us Weekly"When in rear-facing mode, it has an anti-rebound bar that helps eliminate rebound and rotation in collision."

The forward-facing mode uses Rigid LATCH. "That means you get a solid and consistent install in just seconds," says Grayson. "The Clek Foonf is my personal favorite convertible car seat."

The American Academy of Pediatrics recommends turning a child forward-facing no earlier than age 2 — but the Foonf was designed so that kids can ride rear-facing up to age 4 if they're under the 43-inch height limit and 50-pound weight limit. Other key features: Each (recyclable!) seat boasts five harness positions, 10 head rest positions and two crotch buckle positions for optimal safety and comfort.

Mitchell — who is the mom of Kenzie, 3, and Hutton, 15 months — raved about the Foonf in a January 15 Instagram post. “I am a FIRM believer in keeping my loves rear-facing as long as possible!” she wrote, alongside a photo of her smiling tots strapped into their seats.
