Positioning, Comfort & Daily Support

The Matrx PS Cushion is designed for users who need a stable, comfortable seating surface without the maintenance requirements of air, gel, or fluid cushions. Its contoured foam base helps position the pelvis, while the waffled ischial relief area provides targeted relief where seated pressure is often highest.

This makes the PS a strong option for users who need reliable daily support, caregivers who prefer a simple cushion system, or facilities seeking a durable, easy-to-use wheelchair cushion.

Cover Design

The Matrx PS Cushion includes a reversible, machine-washable cover designed for everyday care needs. One side features breathable Startex™ fabric for comfort and airflow, while the smooth side provides a wipeable infection-control surface for easier cleaning. This gives users and caregivers flexibility based on comfort preference, care environment, and moisture-management needs.

Hook-and-loop fastener strips help keep the cushion positioned securely on the wheelchair seat, reducing unwanted movement during daily use.
