Description
The Wedge Cushion with Stretch Cover is a firm high-density foam wedge from Drive DeVilbiss Healthcare, made for a wheelchair seat pan. How it is used on a chair is settled at a seating fit check.
Drive builds one size: 18 in wide by 16 in deep, 4 in high at the back and 2 in at the front, item 8134. See our wheelchair cushions hub, the cushion range, the foam cushions we stock and the Drive brand page.
Who is it for?
- For a wheelchair user whose seat needs a firmer, level base, usually over a sling seat.
- Drive's own words are that the wedge design "helps prevent patient from sliding forward" and that the firm foundation "reduces pressure caused by sling-seat hammocks".
- Tell us the seat pan measurements and what sits on it now, and we check the fit on your chair.
Which size fits?
- Measure the seat pan: this wedge is 18 in wide by 16 in deep.
- It is the only size Drive builds for this wedge, item 8134.
- The height runs from 4 in at the back to 2 in at the front.
- No custom sizes and no colour choices.
How is it built?
- One firm piece of high-density foam, rated by Drive to 250 lb.
- The top cover is a fluid resistant, low shear stretch fabric and the underside is waterproof vinyl.
- Drive publishes no washing instruction for this cover.
What should you know?
Funding may help: see who may help pay. Check the size before you order: a cushion that has been used, or in contact with the skin, may not be returnable. See our return policy.
What does the maker's warranty cover?
Drive gives the wedge a one year limited warranty. Send us the invoice and we handle the claim with the maker.
How does it compare?
| Choice | Build | Where it sits |
|---|---|---|
| Wedge Cushion, this page | Firm foam wedge | Under the seat cushion |
| J2 Series | Foam cushion with a fluid pad | As the seat cushion |
