In one aspect, a seat (100) includes a perimeter frame (109) and a weight bearing surface(112). The perimeter frame (109) includes a front frame member (110b), two contoured lateral frame members (110c, d), and a contoured rear frame member (110a). Each lateral frame member (110c, d) has a front portion, a second portion proximate the user's thighs (155), a concave curve portion (115) proximate the user's pelvis (131), and a rear portion, the bottom of the concave curve portion (115) being lower than the second portion and lower than the rear portion. The rear frame member (110a) has a central dip portion (116). The weight bearing surface (112) on which the user (108) sits includes a plurality of straps (113, 114) attached to the perimeter flame (109). Other aspects relate a method for making a seat (100) and a method for fitting a seat (100) to a user (108). |
