PROBLEM TO BE SOLVED: To provide a folding mattress with the durability for use. SOLUTION: The folding deformable mattress 1 is composed of a plurality of mat blocks 10 arranged in the direction of depth in such a way that the width and the height are constant, and a plurality of folding fulcrums 20 for foldably connecting the mat blocks 10. Each mat block 10 is composed of an upper surface cover 2 disposed on the upper surface, a lower cloth side surface cover 4 disposed on the lower surface, and a cushion material interposed between the upper surface cover 2 and the side surface cover 4. Each folding fulcrum 20 is composed of a partition sewn part where the upper surface cover 2 disposed on the upper surface over a plurality of the cushion materials and the side surface cover 4 disposed on the lower surface over the plurality of the cushion materials are sewn in the cross direction between adjacent faces of the adjacent cushion materials. The storage space formed between the upper surface cover 2 and the side surface cover 4 between the partition sewn parts is formed slightly larger than the cushion material stored in the storage space.
