Eggcrate Wheelchair Seat and Back Cushion 18x32x3 Inch High-Density Foam

A wheelchair cushion that addresses only the seat leaves the back unsupported — and for users who spend extended time in a wheelchair, back discomfort can be just as significant as seat pressure. This eggcrate wheelchair cushion set includes both a seat and back cushion, providing full seating support in a single purchase. The high-density eggcrate foam promotes even weight distribution across the seating surface and allows better air circulation to reduce heat and moisture buildup during extended use. Long-lasting foam construction holds its shape through regular daily use. Sold without cover — a washable or waterproof cover is recommended for clinical and home care use.

Frequently Asked Questions

What is the difference between the seat cushion and the back cushion in this set?
The set includes two separate pieces: a seat cushion that sits on the wheelchair seat pan (17" x 17" x 2.75") and a back cushion that attaches to or rests against the wheelchair backrest. Together they provide cushioning at both the primary pressure points of wheelchair seating — the ischial tuberosities and coccyx at the seat, and the lumbar and thoracic spine at the back. Using both together provides more comprehensive comfort and pressure relief than a seat cushion alone.

Why does eggcrate foam help with pressure relief?
Eggcrate foam has a convoluted surface with peaks and valleys that compress unevenly under the body's weight, distributing pressure across a larger contact area compared to flat foam. This reduces the concentration of pressure at bony prominences — the areas most vulnerable to skin breakdown during prolonged sitting. The convoluted structure also allows air to circulate through the foam, which helps reduce heat and moisture buildup — both contributing factors to skin irritation and breakdown during extended wheelchair use.

Does this cushion come with a cover?
No. This listing is for the foam cushions only — no cover is included. For clinical and home care use, a washable or waterproof cover is strongly recommended to protect the foam from moisture, bodily fluids, and contamination, and to make the cushions easier to clean between uses. Covers should be selected to fit the seat (17" x 17") and back cushion dimensions separately.

Will this cushion fit my wheelchair?
The seat cushion measures 17" x 17", which fits most standard adult wheelchairs with an 18" seat width — the cushion is sized slightly smaller than the seat pan to allow for proper placement without overhang. If your wheelchair has a narrower or wider seat, measure the seat pan before ordering to confirm fit. The back cushion dimensions should also be compared against your wheelchair's backrest height and width to ensure proper coverage.
