Invacare Matrx PS Pediatric Cushion Buyer’s Guide
The Invacare Matrx PS Pediatric Cushion by Motion Concepts is a specialized, high-performance seating solution engineered to provide young wheelchair users with optimal postural stability, pelvic alignment, and skin protection. Designed with lightweight contoured foam and an anatomically shaped ischial relief zone, this pediatric cushion supports proper sitting posture while accommodating active daily use.
Anatomically Contoured Foam Base
The cushion features a sculpted high-resiliency foam core that cradles the pelvis and thighs. This anatomical design distributes weight evenly across the seating surface, helping to reduce interface pressure points while promoting symmetrical alignment and proper spinal posture.
Waffled Ischial Relief Zone
Engineered to protect vulnerable bony prominences, the cushion incorporates a specialized waffled or recessed ischial well. This targeted relief zone helps immerse the pelvic area to minimize shear and peak pressure forces, supporting skin integrity during long periods of seated activity.
Built-In Lateral and Medial Postural Support
Designed with integrated thigh grooves and lateral contours, the cushion prevents unwanted hip adduction or abduction. These built-in positioning controls provide young users with optimal lateral stability and prevent forward sliding within the wheelchair seat.
Reversible Moisture-Resistant Cover
Encased in a durable, fluid-resistant Startex cover, the cushion protects the foam core from spills, moisture, and daily wear. The breathable cover material reduces heat build-up and shear forces against delicate skin while remaining easy to remove and wash for routine hygiene maintenance.
Ultra-Lightweight and Child-Friendly Sizing
Sized specifically for pediatric wheelchair frames, the ultra-lightweight design ensures that adding positioning support does not make the overall wheelchair setup excessively heavy. Its compact footprint allows young users to maneuver their wheelchairs easily and independently.
