Frequently Asked Questions

What does convoluted foam mean?
Convoluted foam has a surface with alternating peaks and valleys — similar in appearance to an eggcrate pattern. This construction allows air to circulate through the foam, reducing heat and moisture buildup during extended sitting. The peaks also compress under the body's weight, distributing pressure across a larger surface area compared to flat foam, which helps reduce pressure concentration at bony prominences.

Does this cushion come with a cover?
No. This listing is for the foam cushion only. A washable or waterproof cover is strongly recommended to protect the foam from moisture and contamination and to make the cushion easier to clean. Select a cover sized to fit the 18 x 16 inch footprint of this cushion.

Will this cushion fit my wheelchair?
The cushion is 16 inches wide and 18 inches long, which fits most standard adult wheelchairs with a 16 or 18-inch seat width. Measure your wheelchair seat pan before ordering to confirm fit. The cushion should sit flat on the seat pan without significant overhang or bunching at the sides.

Can this cushion be used in a chair or recliner, or only in a wheelchair?
While this cushion is sized and designed for wheelchair use, it can also be used in standard chairs, recliners, or other seating where a convoluted foam pressure-relief surface is needed. Confirm that the dimensions are appropriate for your intended seating surface before ordering.
