Convoluted Foam Wheelchair Cushion – 18" x 16", 3" or 4" Height
For wheelchair users who need effective daily pressure relief without the cost or complexity of gel, air, or memory foam systems, the convoluted foam wheelchair cushion with LSII cover is one of the most reliable and widely used options in clinical and home settings. The egg-crate convoluted surface pattern creates multiple contact peaks that distribute seated weight across a broader surface area, reducing pressure concentration at the ischial tuberosities, coccyx, and thighs — the areas most vulnerable to pressure injury during extended wheelchair use. The LSII Low Shear II cover adds a clinical-grade outer layer that reduces skin-damaging friction, resists fluid penetration, and wipes clean quickly.
Who This Is For
- Wheelchair users who spend several hours per day seated and need affordable, consistent pressure distribution
- Users at low to moderate pressure injury risk who need a step up from a standard flat foam cushion
- Seniors using standard wheelchairs, transport chairs, geri-chairs, or recliner chairs
- Care facilities, group homes, and home health agencies looking for a cost-effective, easy-to-maintain pressure relief cushion
- Caregivers replacing a worn, compressed, or soiled cushion on an existing wheelchair
Key Features
- Convoluted Egg-Crate Foam Surface: Multi-point distribution reduces peak pressure at the sit bones and coccyx. Valleys allow air to circulate, reducing heat and moisture buildup.
- Choice of 3" or 4" Height: 3" for lower risk users; 4" for more hours of daily sitting or greater cushioning needs.
- LSII Low Shear II Cover: Two-way stretch fabric reduces shear forces against fragile skin. Fluid-resistant and wipes clean with mild disinfectant.
- Lightweight and Easy to Transfer Between Chairs: Significantly lighter than gel or air cushions of equivalent size.
- Safety Attachment Strap: Secures to the wheelchair frame to prevent sliding during transfers or movement.
- Stable Surface for Trunk Control: Provides enough resistance to support upright seated posture while distributing pressure effectively.
