Cushions used on wheelchairs with a sling seat base have a hammocking effect that lowers their effectiveness and decreases pressure distribution. A rigidizer is inserted underneath the cushion to increase stability and provide a firm base of support to reduce hammocking.
- can be placed inside at the bottom of the cushion cover or underneath it, so it may reduce the need to replace sling wheelchair bases
- easy to setup and use
- can also be used with cushions placed on non-firm chairs or couches
- needs to be roughly the same size as one’s cushion
