<p>PURPOSE:To alleviate the pain of a person weak in the waist or spine or a person suffering from piles at the time of long-time sitting, by arranging the magnet held by the second cushion material in opposed relation to a support means composed of a superconductive substance. CONSTITUTION:When a person sits down on a seat part 6, a sponge cover 4 is pressed downwardly and a sponge layer 3 is compressed by a permanent magnet 5. Since a support plate 2 composed of a superconductive substance not permitting a line of magnetic force to pass is arranged under the sponge layer 3, the permanent magnet 5 is upwardly repelled and soft elastic force is obtained. In the same way, when a person leans against a backrest part 16, the sponge cover 14 is pressed rearwardly and a sponge layer 13 is compressed by a permanent magnet 15. Since a support plate 12 composed of a superconductive substance is arranged behind the sponge layer 13, the permanent magnet 15 is forwardly repelled and soft elastic force is obtained. Further, since the permanent magnets 5, 15 are arranged to the back surfaces of sponge covers 4, 14, a line of magnetic force acts to improve blood circulation.</p> |
