To provide a mattress for reducing a difference of a body pressure dispersion effect to be generated depending on a use direction when a user applies a body weight.SOLUTION: A mattress 1 has a predetermined thickness in a thickness direction and a front surface 2 is extended in a plane direction orthogonal to the thickness direction. In the thickness direction, the mattress has a plurality of projections 3 where three layers being the first layers 31, the second layers 32, and the third layer 33 are laminated from the front surface 2. The projections 3 are consecutively formed in the plane direction. In the projections 3, the first layers 31 are consecutively arranged and the second layers 32 have density and/or hardness lower than those of the first layers 31 and the third layer 33. The first layers 31 may have regular projections/recessions in the thickness direction.SELECTED DRAWING: Figure 1 【課題】使用者が体重をかけたとき、使用する方向によって生じる体圧分散効果の差を低減するマットレスを提供すること。【解決手段】マットレス１は、厚み方向に所定の厚さを有し、表面２が厚み方向に直交する平面方向に広がる。厚み方向は、表面２から第一層３１と第二層３２と第三層３３の三層が積層する複数の凸条３を備える。凸条３は、平面方向に連続して形成される。凸条３において、第一層３１が連続し、第二層３２は、第一層３１及び第三層３３よりも、低密度及び／又は低硬度である。第一層３１は、厚み方向に規則的な凹凸を有してもよい。【選択図】図１
