A folding support constructed from arrays of interdigitated elongated members. The interdigitated elongated members are not hinged or joined together in any way, but rather are free to slide with respect to each other. The elongated members are joined to end pieces to form the arrays. A seat extends between the end pieces and rods or flexible members may be used to define the angular position between the arrays.
