Clek Fllo is a safe narrow convertible car seat that supports extended rear-facing use. Engineered to protect, it is built with advanced safety features, including a steel anti-rebound bar, Clek’s patented EACT energy management system, and advanced side-impact protection, with deep side wings, energy-absorbing foam layers, and an adjustable structural headrest. Plus, at less than 17 inches wide, Fllo’s narrow design makes it easy to ride 3-across.
