Invacare Matrx Vi Heavy Duty Cushion Buyer’s Guide
The Invacare Matrx Vi Heavy Duty Cushion by Motion Concepts is a high-performance wheelchair seat cushion engineered to provide skin protection, pelvic positioning, and pressure relief. Specifically built for bariatric users and individuals at moderate-to-high risk of skin breakdown, this heavy-duty cushion combines a three-part foam construction with a 600 lb. weight capacity to ensure stability, comfort, and safety during extended seating.
Three-Part Dual-Density Foam Construction
The cushion features an anatomically contoured three-layer foam core designed to address critical pressure points. The top layer utilizes high-resiliency foam treated with Ultra-Fresh™ antimicrobial protection to prevent odors and bacteria, while the firm bottom layer prevents bottoming out and maintains structural integrity.
Invacare Matrx Vi Visco-Elastic Ischial Insert
At the heart of the cushion’s skin protection system is a molded visco-elastic foam insert anatomically targeted to the ischial and sacral regions. This pressure-relieving insert allows sensitive bony prominences to immerse safely into the cushion, effectively redistributing weight and reducing the risk of pressure ulcers.
Invacare Matrx Vi Heavy Duty Weight Capacity
Engineered for robust support, the heavy-duty model supports up to 600 lbs. It is available in expanded seat widths ranging from 18 inches up to 30 inches and depths up to 26 inches, providing a secure fit for bariatric wheelchair frames.
Anatomical Contouring and Pelvic Stability
Built-in abductor and adductor contours promote midline leg positioning, while a pre-ischial contour prevents pelvic tilt and forward sliding. A trochanteric shelf adds lateral hip stability, and the waterfall front edge reduces pressure behind the knees for improved circulation and hock clearance.
Dual Cover System for Hygiene and Protection
The cushion comes standard with a dual-layer cover setup:
-
Inner Cover: Moisture-resistant and easy to wipe clean, featuring a zippered closure that allows quick access for custom foam modifications.
-
Outer Cover: Breathable, moisture-resistant fabric paired with a slip-resistant base, hook-and-loop fasteners, and a built-in lifting strap for effortless handling.
