A seat cushion includes a hard baseboard, a gel, a foam and an enclosure portion. The hard baseboard has an upper surface. A convex portion is formed on the front part near the central part of the upper surface. A concave portion is formed on each side of the convex portion. An upwardly extending portion is formed on each of the two corners of the rear part of the upper surface, and an indent part of the rear part of the hard baseboard is formed between the two upwardly extending portions, so that the hard baseboard mimics the shape of a user's hip and thighs in sitting position. The gel and the foam may be disposed in various configurations on the baseboard. |
