McKesson Premium Gel Seat Cushion with Molded Foam - 275lb Capacity
McKesson Triple-Layer Gel & Molded Foam Seat Cushion (18" x 16" x 3")
Triple-Layer Ergonomic Pressure Redistribution Architecture with Gel-Infused Memory Foam Top, Molded Leg Troughs, Trochanter Cutouts, and 275 lb Rating
The McKesson Gel Seat Cushion with Molded Foam (SKU: 170-77002) delivers a clinically advanced pressure-redistribution and anatomical positioning seating solution meticulously engineered for wheelchair users seeking superior comfort during extended sitting. Extended wheelchair sitting creates concentrated interface pressure at the sit bones (ischial tuberosities) and tailbone (coccyx). Standard flat foam cushions can bottom out over time, leaving users vulnerable to skin irritation, posture collapse, and tissue breakdown. This high-performance cushion overcomes those daily seating challenges, utilizing a triple-layer core that molds to body contours and distributes pressure evenly across an 18" x 16" surface.
Constructed with a pressure-sensitive molded high-density polyurethane foam base encasing an interior gel bladder, the cushion is topped with a layer of gel-infused visco memory foam. This top layer allows pressure points to submerge comfortably while open-cell breathability combined with cooling gel agents regulates skin surface temperature. Anatomically shaped with molded leg troughs, trochanter cutouts, and a raised front ridge, the cushion promotes proper hip and femur alignment to prevent sliding. Wrapped in a breathable, low-shear stretch nylon cover with a fluid-resistant barrier and adjustable anchor buckle straps, this 275 lb capacity cushion offers complete, latex-free protection for daily wheelchair mobility.
Key Features & Benefits
- Advanced Triple-Layer Core: Combines a molded high-density polyurethane foam base, an internal pressure-relieving gel bladder, and a top layer of gel-infused visco memory foam for maximum immersion.
- Anatomical Positioning Contours: Built-in trochanter cutouts, molded leg troughs, and a raised front abductor ridge keep hips aligned, stabilize the pelvis, and prevent forward sliding.
- Temperature & Moisture Regulation: Gel-infused open-cell memory foam absorbs body heat while promoting airflow to maintain a cool, dry microclimate against the skin.
- Low-Shear Fluid-Resistant Cover: Breathable stretch nylon top cover reduces friction and shear forces on fragile skin while an internal waterproof barrier protects the inner foam matrix from spills and incontinence.
- Easy Maintenance Zipper Cover: Removable outer cover unzips smoothly for quick machine washing, simplifying hygiene routines for caregivers and users.
- Secure Frame Attachment: Adjustable positioning straps with quick-release buckles keep the cushion anchored firmly to the wheelchair seat frame during transfers.
- 275 lb Weight Capacity & Latex-Free: Tested for safe, active support up to 275 lbs and manufactured without natural rubber latex to prevent allergic skin reactions.
Equipment Specialist Insight: The combination of gel-infused memory foam and contoured leg troughs gives this cushion a major advantage in posture stability. The molded channels gently guide the thighs into a neutral alignment, which helps keep the pelvis level and prevents the user from sliding forward into a sacral sit. For proper setup, ensure the raised front ridge faces forward and secure the rear buckle straps snugly around the wheelchair's back posts.

Frequently Asked Questions
How do I wash and care for the cushion and cover?
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 line 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 inner foam core.
What is the benefit of the gel-infused visco memory foam top layer?
Traditional memory foam can trap body heat, causing perspiration and skin breakdown over extended sitting periods. Infusing open-cell visco foam with cooling gel agents provides the pressure-molding immersion of memory foam while actively drawing heat away from the body to keep the seating surface cool and dry.
Will this 18" x 16" cushion fit standard wheelchairs?
Yes. An 18" width by 16" depth is the standard dimension for most adult wheelchairs. Measure your wheelchair seat frame from armrest to armrest and back posts to front seat edge before ordering to ensure a proper, snug fit.
