A flexible support structure of a seat cushion, such as a wheelchair cushio n, has an upper surface with a support contour having relief areas for establishing relatively less pressure on skin adjacent to bony prominences of a user's pelvis and having a support area for establishing relatively more pressure on skin covering a tissue mass spaced from the bony prominences. A slit is formed in the rear corner of the support structure and an insertion member is inserted int o the slit to change a position of the support area to thereby adjust the support conto ur for better support of the pelvic area. A cover encases the support structure to resist outward deformation of the support structure. The cover has an extension portion that expands the cover at the rear corner to increase a dimension of the cov er to encase an increase dimension of the corner caused by the insertion of the insertion member.
