Abstract
Abstract A mattress for magnetic treatment which produces magnetic treatment effects by permanent magnets and chiropractic effects by protuberances while sleeping. The mattress therefore comprises an elastic body of crosslinked foamed polyethylene, foamed urethane or the like, the elastic body having protuberances on its surface for producing chiropractic effects, damper felt fixedly secured to the surface of the elastic body, the damper felt being dotted with permanent magnets, a fiber layer fixedly secure to the surface of the damper felt and used for holding the permanent magnets and the protuberances of the elastic body, and a thin soft fiber layer covering the surface of the fiber layer. The elastic body comprises short and tall barrel-like bodies, these being disposed at fixed intervals.
