A seating unit (50) includes a perimeter frame (90), a flexible seating surface supported by the frame, and parallel elongated resilient force-distributing members (103) coupled to the seating surface to control a contour of the seating surface when supporting a user. The resilient force-distributing members (103) are bendable along their length and are sufficient in number and distribution to substantially reduce localized deflection of the seating surface and thereby reduce pressure point contact felt by the user. The resilient force-distributing members (103) can be wire rods, long strips, or other resilient material with memory. The resilient force-distributing members (103) can be supported on opposing sides of the perimeter frame in various ways to reduce inward pressure on the opposing sides during flexure of the resilient force-distributing members (103).
