McKesson Gel Seat Cushion with Molded Foam, 22 x 18 x 3 Inch
McKesson Heavy Duty Gel Seat Cushion with Molded Foam (22" x 18" x 3")
Ultra-High Density Molded Polyurethane Foam Matrix with Anti-Migration Interior Gel Bladder, Low-Shear Stretch Nylon Cover, and 350 lb Load Rating
The McKesson Heavy Duty Gel Seat Cushion with Molded Foam delivers an advanced pressure-redistribution and postural support seating solution meticulously engineered for individuals requiring maximum comfort during extended wheelchair sitting. Prolonged wheelchair use creates concentrated interface pressure on the sit bones (ischial tuberosities) and tailbone (coccyx). Standard flat foam cushions can compress flat under sustained loads, leaving users vulnerable to painful pressure sores and tissue breakdown. This high-performance heavy-duty cushion overcomes those daily risks, utilizing a dual-action gel and foam construction that distributes body weight evenly across a 22-inch wide surface.
Constructed with an ultra-high density molded polyurethane foam shell surrounding an interior gel bladder, this 3-inch thick cushion features an anti-migration design that keeps the gel centered under weight rather than pushing out to the sides. The heat-absorbent gel dissipates body heat and moisture to optimize the skin microclimate during extended use. Wrapped in a breathable, low-shear stretch nylon cover with a waterproof barrier and a skid-resistant gray bottom, the cushion includes adjustable buckle straps to anchor firmly to the wheelchair frame. Supporting up to 350 lbs, this 100% latex-free seat cushion provides long-lasting, hygienic protection for daily mobility setups.
Key Features & Benefits
- Anti-Migration Gel Bladder Technology: Internal gel core is engineered to eliminate gel displacement, maintaining balanced, centered pressure relief right where support is needed most.
- Ultra-High Density Molded Foam Shell: Encasing polyurethane foam provides structural stability and deep immersion support to prevent bottoming-out under body weight.
- Cooling Microclimate Control: Heat-absorbing gel matrix absorbs excess body heat to minimize perspiration and regulate skin surface temperatures during long sitting periods.
- Low-Shear Waterproof Stretch Cover: Breathable top cover stretches to reduce friction and shear forces on fragile skin, while an internal fluid-resistant barrier shields the core from spills and incontinence.
- Skid-Resistant Bottom & Secure Straps: Non-skid gray base material paired with adjustable buckle attachment straps keeps the cushion firmly anchored to the wheelchair seat frame.
- Easy-Care Machine Washable Cover: Outer cover features a smooth zipper closure for quick removal and machine washing to simplify hygiene.
- Heavy-Duty 350 lb Weight Capacity: Reinforced structural build supports active user loads up to 350 lbs for wide-frame wheelchair mobility.
- 100% Natural Rubber Latex-Free: Formulated without natural rubber latex to protect users against skin sensitivities and allergic reactions.
Equipment Specialist Insight: Gel-foam cushions excel at combining the immersion properties of gel with the posture support of dense foam. McKesson's anti-migration bladder design solves a common issue with traditional gel cushions—where gel moves away from high-pressure points over time. For best results, place the cushion with the non-skid gray surface facing down on the seat sling and tighten the buckle straps around the rear frame posts to prevent the cushion from shifting during transfers.

Frequently Asked Questions
How do I clean and maintain the cushion cover and core?
Unzip and remove the stretch nylon cover, then machine wash it in cool or warm water with a mild detergent on a gentle cycle. Tumble dry on low heat or air dry. The inner foam and gel core are protected by a fluid-resistant barrier—simply wipe down the inner surface with a damp cloth and mild disinfectant if needed. Do not submerge or machine wash the foam core.
What is the purpose of the anti-migration gel bladder?
Standard gel cushions can suffer from "gel migration," where the gel shifts outward away from pressure points under body weight, leaving the user sitting directly on the underlying foam. The anti-migration design uses segmented chambers inside the bladder to keep the gel locked beneath the sit bones, ensuring consistent pressure redistribution over time.
Will this 22" x 18" cushion fit standard wheelchairs?
This 22" W x 18" L cushion is designed for wide or heavy-duty wheelchairs with a 22-inch seat width and 18-inch seat depth. Measure your wheelchair seat frame from armrest to armrest and back posts to front seat edge before ordering to ensure a proper, snug fit.
