Invacare Matrx PS Cushion Buyer’s Guide
The Invacare Matrx PS Cushion by Motion Concepts is a premium postural support and pressure-relieving wheelchair cushion engineered for high-level skin protection and pelvic stability. Featuring an anatomically molded foam base with a ischial relief recess, this cushion is ideal for individuals at risk of skin breakdown who require lightweight, comfortable, and therapeutic seating support.
Anatomically Molded Foam Core
The Invacare Matrx PS Cushion is constructed from high-resiliency, molded foam that provides targeted body contouring. Its anatomical design distributes user weight evenly across the sitting surface, reducing peak pressure points under bony prominences to help prevent tissue breakdown and pressure ulcers.
Deep Ischial Relief Recess
Designed specifically for skin protection, the cushion incorporates a carved ischial well that cradles the pelvic region. This specialized recess relieves pressure on the ischial tuberosities and sacrum, promoting pelvic alignment and enhancing seated posture for extended daily use.
Invacare Matrx PS Cushion Built-In Trochanteric Support
The contoured surface features raised lateral edges and a subtle medial thigh trough to guide leg positioning. This built-in support stabilizes the trochanters and thighs, preventing hip rotation, forward sliding, and asymmetrical posture.
Moisture-Wicking and Moisture-Resistant Cover
Encased in a multi-stretch, breathable outer cover, the cushion reduces skin shear and friction during user movement. The cover features a moisture-resistant inner lining to protect the interior foam from fluid ingress while remaining easy to remove and machine wash for routine hygiene maintenance.
Lightweight and Durable Wheelchair Fit
Engineered to fit standard wheelchair seat sizes seamlessly, this cushion offers long-lasting durability without adding unnecessary weight to the mobility system. Its durable foam density resists packing down over time, maintaining consistent posture control and skin protection.
Invacare Matrx PS Cushion Review
The Invacare Matrx PS Cushion by Motion Concepts is an outstanding choice for users needing advanced postural control combined with skin care protection. Its anatomically molded foam, deep ischial recess, and shear-reducing cover provide a reliable, long-term seating solution for daily wheelchair users.
