Invacare Matrx PSP Pediatric Cushion Buyer’s Guide
The Invacare Matrx PSP (Posture Seat Polymer) Pediatric Cushion by Motion Concepts is a specialized seating solution engineered to deliver targeted skin protection, pelvic positioning, and shear reduction for active children in manual or power wheelchairs. Built on a high-resiliency contoured foam base with a molded polymer overlay, this lightweight, low-maintenance cushion supports healthy posture and pelvic stability while minimizing the risk of skin breakdown.
Dual-Layer Polymer and Foam Construction
The Matrx PSP Pediatric Cushion combines a high-resiliency molded foam base with an integrated, molded polymer overlay. This dual-layer design provides structural stability for proper sitting postures while enhancing surface immersion and dramatically reducing shear forces during movement.
Waffled Ischial Relief Recess
To protect delicate skin over pelvic bony prominences, the cushion features a unique waffled ischial relief recess. This specialized relief area enables bone immersion, offloads interface pressure away from the hips and sacrum, and prevents forward sliding in the wheelchair.
Anatomical Contouring and Waterfall Front Edge
Designed to keep young users properly aligned, gentle leg troughs and side contours guide the legs into a neutral position. The waterfall front edge eases pressure behind the knees and hamstrings, making transfers smoother and supporting independent foot propulsion when needed.
Ultra-Fresh™ Antimicrobial Foam Core
The high-resilience polyurethane foam is treated with Ultra-Fresh™ antimicrobial protection. This built-in treatment guards against odor-causing bacteria, mold, and mildew, ensuring long-term hygiene and fresh performance throughout daily use.
Reversible Startex™ Dual-Surface Cover
Encased in a versatile, two-sided Startex™ outer cover, caregivers can alternate between a soft, breathable fabric side for cool airflow or a smooth, wipeable infection-control side for quick cleaning. A moisture-resistant inner cover provides an extra layer of protection for the foam core.
Zero-Maintenance Lightweight Reliability
Unlike air or fluid-filled pediatric cushions that require frequent monitoring, inflation, or gel adjustment, the Matrx PSP Cushion is a zero-maintenance, worry-free solution. Weighing under 2 lbs, it keeps total chair weight low without compromising skin protection.
Invacare Matrx PSP Pediatric Cushion Review
The Invacare Matrx PSP Pediatric Cushion provides an outstanding blend of postural support, skin protection, and low-maintenance convenience for growing children. Its anatomical contouring, polymer overlay, and dual-sided moisture cover make it a reliable choice for home, school, and everyday mobility
