- **Price:** £363.5 [^1]
- **Summary:** The Clek Foonf is a convertible car seat designed for extended rear-facing and forward-facing use, with an adjustable headrest and a steel anti-rebound bar for rear-facing. It uses the REACT rigid-LATCH energy absorbing crumple system for forward-facing protection and is built to fit three-across due to its narrow 16.9 in width. It's suited for children who can sit upright alone and stay rear-facing for as long as possible, then move forward-facing when ready.
- **Ideal For:** It's a convertible seat with REACT (Rigid-LATCH energy absorbing crumple) plus Ziip FR-Free/PFAS-Free fabric options, including Mammoth Ziip made with merino wool and Tencel, supporting the 'sustainable materials' angle while still targeting extended rear-facing and forward-facing safety specs.
