Abstract

This invention will focus on the fu, which has a futon (1) which has a core part. Made of rigid molded foam of sufficient thickness. or hollow synthetic resin Shaped with a hard mold and there is an elastic surface layer (6),(7) with plates (4), (5) placed on both sides of the core (3) in a dovetailed manner in the middle. At least a surface layer (6), (7) is formed by placing the first layer (10) cushioning layer of soft cushioning material overlaid with the cushioning layer. (11) made of secondary material It receives a semi-rigid cushion with a concave and protruding surface (13) on its surface on the protective sheet (4). In conventional mattresses, due to the multiple coil springs attached firmly attached to the metal frame Therefore, the weight is quite large. In this invention, since it is not a metal part, it uses rigid mold-formed foam and rigid mold-formed hollow synthetic resin as its core (3). It is light and has no problems with rusting and tearing. In addition, due to the use of the concave and protruding surface (13) of the second cushioning layer (11) on the surface to support the body as the contact point, it is waterproofed. good and finger pressure is generated from the protrusion (14), improving health
