When evaluating foldable reclining chairs, prioritize the frame material, typically powder-coated steel or high-grade aluminum, to ensure a balance between weight and structural integrity. The weight capacity should be at least 120kg to 150kg for standard consumer safety. Additionally, check the locking mechanism (e.g., ring-lock or tooth-gear system) to ensure it provides multi-angle stability without slipping. For outdoor use, ensure the fabric is UV-resistant and quick-drying, such as Textilene or 600D Oxford cloth with PE/PVC coating.
