Matrx VI Heavy-Duty Cushion

The Invacare Matrx Vi Heavy-Duty Cushion is a bariatric wheelchair cushion designed to provide skin protection, pelvic stability, and everyday comfort for users who require larger seating dimensions and higher weight capacity. Built with the same three-part foam construction as the standard Matrx Vi, the Heavy-Duty version combines a soft high-resilience foam top layer, a molded visco-elastic ischial relief insert, and a firm high-resilience foam base to target pressure relief, support, and durability where they are needed most.

Designed to support users up to 600 lbs., the Matrx Vi Heavy-Duty offers larger cushion sizes while maintaining the positioning-focused design of the Vi series. Its contoured shape helps support pelvic stability, midline leg positioning, hip alignment, and reduced forward sliding, making it a practical option for users who need advanced foam-based pressure relief in a heavier-duty configuration.

• Soft HR Foam Top Layer: Provides comfort and support, with contours that help stabilize the pelvis and promote midline leg positioning. Made with Ultra-Fresh™ antimicrobial and odor protection
• Visco-Elastic Relief Insert: Anatomically targeted to the ischial and sacral area to help immerse sensitive bony prominences and improve pressure relief

Heavy-Duty Skin Protection & Positioning Support

The Matrx Vi Heavy-Duty Cushion is designed for users who need the skin protection and stability of the Matrx Vi in a larger, higher-capacity format. The visco-elastic insert provides targeted immersion in the ischial and sacral region, while the contoured foam base helps maintain pelvic alignment and reduce sliding.

This makes the Vi Heavy-Duty a strong option for bariatric users, long-term wheelchair users, and care environments where a durable, low-maintenance cushion is needed for daily seating.

Optional outer cover upgrades are available, including Moisture Resistant Startex™ Fabric and Wipeable Startex™ Infection Control.
