Abstract (en)
A magnetic levitation cushion has multiple magnetic levitation devices (1) being assembled with at least one bracket (2). Each magnetic levitation device (1) has a housing (10), a fixed magnet (14), a movable magnet (15), a shaft (16) and a primary pad (17). The fixed magnet (14) is mounted securely in the housing (10). The movable magnet (15) is mounted slidably in the housing (10) and faces the fixed magnet (14) with a same magnetic pole. The shaft (16) is mounted slidably through the housing (10) and has a bottom end attached to the movable magnet (15). The primary pad (17) is mounted on a top end of the shaft (16). The magnetic levitation cushion is used for upholstered furniture such as chairs, beds and sofas and does not suffer metal fatigue or material hardening problems and may be cleaned, rearranged and recycled effectively.
