McKesson Seat Cushion, 20" W x 18" L x 3" D, Standard

The McKesson Seat Cushion is designed to provide reliable pressure relief and everyday comfort for wheelchair users, caregivers, and anyone who spends extended time seated. Made from high-density polyurethane foam, this cushion helps reduce the risk of pressure sores while offering a supportive, ultra-lightweight seating surface that's easy to transport from room to room or during travel.

Measuring 20" W x 18" L x 3" D, this standard-size cushion fits comfortably into most wheelchairs and seating systems. Adjustable safety straps help keep the cushion securely in place, adding an extra layer of stability and confidence during transfers or movement. The high-resilience foam is engineered to absorb shock and minimize impact from uneven terrain, supporting users up to 250 lbs.

Practical, everyday use is made easier with a low-shear, stretch nylon cover that's both breathable and waterproof — ideal for managing spills, perspiration, or incontinence-related concerns. The durable gray bottom adds skid resistance for added safety, while the unzip-and-wash design makes routine cleaning simple and low-maintenance. This wheelchair seat cushion is a smart, budget-friendly choice for anyone seeking daily comfort without compromising durability.
