PROBLEM TO BE SOLVED: To obtain a foldable and stretchable mat with excellent heat insulation and skin touch feeling, by using elastic cloth as a cover material and constituting the border between a back rest and a lower part to be elastic and foldable. SOLUTION: This mat 1 comprises a back rest 2 and a lower half body part 3 whose cushion materials 4, 5 are covered by cover materials 6 and a border part 7 between the back rest part 2 and the lower half body part 3 is sectioned by a cover material 63 and mutually connected. The cover materials 6 are to give good skin touch feeling to the surface of the mat 1 and is comprises elastic cloth. Further, the skin touch feeling felt on the surface of the mat 1 and the heat retaining property by heat insulation can be improved by laminating a foam sheet 8 on the back side of the cloth or putting the foam sheet 8 in between doubled cloth. The thickness of the foam sheet 8 is required to be selected considering heat insulation and heat retaining properties, foldability, and elasticity. |
