Invacare Matrx PS Heavy-Duty Cushion Buyer’s Guide
The Invacare Matrx PS Heavy-Duty Cushion by Motion Concepts is an ultra-lightweight, high-capacity wheelchair seating surface engineered specifically for bariatric users requiring anatomical positioning, pelvic stability, and skin protection. Built with high-resiliency molded foam and featuring a specialized waffled ischial relief area, this cushion provides reliable pressure management without the maintenance demands of fluid or air-based systems.
High-Resilience Molded Foam Core
The Invacare Matrx PS HD Cushion utilizes a durable, high-resilience foam foundation that prevents "bottoming out" under heavy daily use. The foam is treated with Ultra-Fresh™ antimicrobial and odor protection to prevent bacterial growth and maintain hygienic freshness over time.
Waffled Ischial Relief Recess
Designed for optimal pressure redistribution, the cushion incorporates a unique waffled recess at the rear ischial zone. This anatomical relief cutout allows bony prominences to immerse comfortably into the cushion, minimizing peak pressure points and reducing forward pelvic sliding.
Anatomical Contouring and Leg Troughs
The cushion features built-in trochanteric shelves, a rear sacral radius, and subtle leg troughs to guide lower extremity alignment. Its waterfall front edge reduces pressure behind the knees, accommodating tight hamstrings and facilitating foot propulsion when necessary.
Innovative Reversible Dartex® Outer Cover
Encased in a multi-functional Dartex® outer cover, the surface can be reversed based on user preference: one side offers breathable fabric for cooling airflow, while the opposite side provides a smooth, wipeable infection-control surface.
Moisture-Resistant Inner Liner
To protect the internal foam core from spills and incontinence, the cushion includes a zippered, moisture-resistant inner cover. This inner layer wipes down easily with standard disinfectants, simplifying daily maintenance for caregivers.
Invacare Matrx PS Heavy-Duty Weight Capacity
Engineered specifically for bariatric seating systems, the Heavy-Duty model supports user weight capacities up to 600 lbs while accommodating larger seat dimensions ranging from 21 inches to 30 inches in width.
Invacare Matrx PS Heavy-Duty Cushion Review
The Invacare Matrx PS Heavy-Duty Cushion by Motion Concepts provides an exceptional balance of posture control, low-maintenance pressure management, and bariatric weight support. Its combination of contoured foam, ischial offloading, and dual-sided moisture protection makes it a premier choice for active or full-time wheelchair users.
