Covers wear out long before the back support does. This is the spare outer cover for the Spex SuperShape back support, so a chair that is still correctly set up can be kept in service with a fresh cover.
It is the expansion fabric cover, which is what lets the SuperShape contour around asymmetry without pulling tight across skin. Keeping a spare on hand means a client is not sitting in a soiled or damaged cover while a replacement is ordered.
The cover is breathable and washable, which suits clients who spend long days in the chair or who perspire heavily. It is size specific, so it needs to match the width and height of the back support already fitted.
