PROBLEM TO BE SOLVED: To provide a mattress device capable of securely supporting a heavy part, or the like of a user's body while applying a soft touch to the user. SOLUTION: The mattress device includes: a plate-shaped mattress body 5 made of an elastic material; storage parts 6-8 opened on the upper surface of the mattress body, whose inner surfaces are formed as first inclined surfaces 6a-8a inclined outward toward the upper surface of the mattress body; and pads 11-13 made of an elastic material softer than the mattress body and formed in shapes corresponding to the storage parts. The outer surfaces of the pads are formed as second inclined surfaces 11a-13a corresponding to the first inclined surfaces. The pads 11-13 are stored in the storage parts with the second inclined surfaces in contact with the first inclined surfaces. COPYRIGHT: (C)2010,JPO&INPIT
