Abstract
A wheelchair back system provides height adjustability of the back, adjustment of the tilt and a lumbar support for a user. The back system is removably-affixed to vertical wheelchair posts by pairs of upper and lower channels at the lateral edges of the back. One of the channels on each side is open to the rear and the other of said channels is open to the front, whereby the channels engage the wheelchair posts. A clip, affixed to the rear side of the wheelchair posts, releasably engages the front opening channels to secure the back in engagement with the wheelchair post.
