Abstract

Abstract A mattress (futon or thick bedquilt) and bedclothes, or a pillow which comprises fillings, a plurality of permanent magnet pieces provided on a mounting means, and a covering cloth for covering the above-mentioned components. These magnet pieces generate lines of magnetic force and which are projected on a user's head or other portions of his body thereby to improve the user's health. On the other hand, these magnet pieces abut on the user's body through its covering cloth at the time of applying these mattress and bedclothes as well as pillow, thereby effecting functions of finger-pressure. Further since the pillow contains a heat-absorptive material such as adzuki beans as the fillings, such pillow functions to keep a user's head cool and his feet warm.
