An adjustable back system for releasable attachment to spaced-apart substantially vertical wheelchair frame posts (52). The back system includes a relatively rigid shell back (36) formed to extend transversely between the posts (52) for support of a user\s back, a plurality of post-engaging assemblies (50) coupled to shell back (36) by a plurality of independently adjustable coupling assemblies. The post-engaging assemblies (50) including an upper pair of post-engaging assemblies extending transversely from opposite sides of shell back (36) and a lower pair post-engaging assemblies extending transversely from opposite sides of shell back (36) below upper post-engaging assemblies. The post-engaging assemblies (50) each are formed to releasably secure shell back (36) to the posts (52), and the adjustable coupling assemblies are formed for independent fore and aft adjustment of the position of coupling of post-engaging assemblies (50) for adjustment of the angle and depth at which shell back (36) is mounted to posts (52). The adjustable coupling assemblies further including connecting members (79) extending between upper post-engaging assembly and lower post-engaging assembly on each side of shell back (36), the connecting members (79) being formed to rigidly interconnect the coupling assemblies to enable fore and aft adjustment of the depth of shell back (36) relative to posts (52) while maintaining substantially the same angle of shell back (36) relative to posts (52).
