Safe - The flexible seat curves to a flat surface that lifts you up on a level plane. This patented LeveLift design provides for a safe lift up, with no forward dumping motion. Patent # 5,316,370
Durable - The injection-molded base is made of durable polycarbonate, and covered with a non-slip material that prevents shifting on fabric seating surfaces.
Waterproof - The breathable fabric cover is waterproof and machine washable in cold water. Comes in black.
Easy Care - The foam cushion has a water resistant coating that can be wiped down with mild soap and water.
Self-Powered - A hydro-pneumatic gas spring serves as the lifting mechanism, releasing automatically when you begin to stand. No battery or electricity required.
