PROBLEM TO BE SOLVED: To provide a single body type mat 1 for bedding moulded of soft urethane foam of a single material by profiling work in which a head part, a waist part, and a leg part of a person in a sleeping attitude can be properly supported in accordance with respective body pressure, in which finger-pressure treatment effect and ventilation performance are excellent to provide improved sleeping comfortableness. SOLUTION: For three parts 2-4 parted along the longitudinal direction of a mat 1 to correspond to a head part, a waist part, and a leg part, irregularity surfaces of three-dimensional curvatures of different outer forms from each other are formed on the mat surface, so the three parts 2-4 are provided with different hardness from each other. Favorably, hardness ratio for three parts 2-4 corresponding to the head part, waist part, and leg part is set to be (1.0-2.0):(1.1-3.0):1.0. It may otherwise comprise a mat lamination body comprising an upper and a lower mat layers of different surface outer forms and hardnesses from each other, and a middle mat layer of a larger hardness laminated on each other for the three parts 2-4. |
