PROBLEM TO BE SOLVED: To secure a permeability to prevent a bedsore by forming a plurality of ridge-shaped projected parts on the surface of a seat in parallel in the longitudinal or lateral direction of the seat to prevent a stick adherence between a human body and the seat through groove parts formed at least among ridge- shaped projected parts. SOLUTION: In a bedsore preventing seat, a seam 1 is formed from a longitudinal side 10a to its opposite side 10b, and a seam 2 is formed from a lateral side 10c to its opposite side 10d. Each of the front and the rear material 15, 16 of the seat 10 is a cotton texture, and the ridge-shaped projected parts 11 of the seat 10 to continue from the longitudinal side 10a to its opposite side 10b are formed of a padding 13 which is plurally arranged in parallel between the front material 15 and the rear material 16 through a cushion material, for instance, in parallel in order in a longitudinal direction on the surface of the seat 10. The padding 13 is internally fitted between seams 1, 1 from the longitudinal side 10a to its opposite side 10b, and the longitudinal movement of the padding 13 is controlled by the seam 2 from the lateral side 10c to its opposite side 10d to prevent positional slippage. |
