The Norwegian-designed Backapp Hipp is designed to add active comfort to offices, home offices and meeting rooms. The environmentally-friendly and lightweight plastic seat is contoured to perfectly fit the body, while the seat plate is soft and flexible for a truly natural feel while you work. The unique damping device ensures soft movements while the adjustable ball can be used to tweak the level of stability you require while you sit - the less stability, the more your core has to work. The materials have been specifically selected for ease of recycling, allowing you to easily disassemble them for reuse when the time comes.
