<p>PROBLEM TO BE SOLVED: To provide bedding such as a futon which can maintain and improve heat insulation performance with heat insulation grains and inhibit leakage of the heat insulation grains from a futon outer surface.SOLUTION: A futon 100 is provided with a futon outer surface 101. The futon outer surface 101 is for containing a heat insulation material 104 with a holding bag 102 and consists of a cloth material of bag-like shape. The holding bag 102 is a bag for holding a heat insulation material 104 in the futon outer surface 101. A heat insulation layer 103 formed by vapor-depositing aluminum material is formed on the outer surface of the holding bag 102. The heat insulation material 104 is composed of cotton and has heat insulation grains 105 in interspace of the cotton. The heat insulation grains 105 are a member for maintaining and improving heat insulation performance of the heat insulation material 104 and composed of plural kinds of granular materials of resin-foam having different sizes each other.</p> |
