Matrx Libra Fit Kit by Motion Concepts Buyer’s Guide
The Matrx Libra Fit Kit by Motion Concepts is a modular seating accessory designed to enhance pressure redistribution, pelvic stability, and postural alignment for users of the Invacare Matrx Libra Wheelchair Cushion. Engineered for clinical customization, this accessory kit allows therapists and ATPs (Assistive Technology Professionals) to fine-tune cushion contours to accommodate or correct pelvic obliquities, rotations, and leg length discrepancies.
Modular Component Design for Targeted Customization
The kit includes a comprehensive assortment of anatomical foam shims and fluid supplements, providing targeted support right where it’s needed:
-
Fluid Accessories: Two supplemental fluid packs for enhanced ischial/sacral immersion and skin protection.
-
Tapered Wedge (1" / 25 mm): Accommodates pelvic tilt and hip flexion requirements.
-
Pelvic Obliquity Accessories: Two 0.5" (13 mm) shims to address unlevel pelvic alignment.

Matrx Libra Fit Kit Pelvic & Postural Alignment
By pairing custom shims with the Matrx Libra Cushion’s base contour, the kit helps eliminate unwanted pelvic rotation, forward sliding, and pressure hot spots. This precise alignment reduces tissue shear, improves sitting balance, and enhances comfort during extended periods in a wheelchair.
Seamless Integration & Tool-Free Adjustment
Designed specifically for the Matrx Libra Cushion, every component fits neatly beneath or within the cushion's dual-cover system. The shims can be placed, repositioned, or trimmed without special tools, allowing quick adjustments during routine seating evaluations.
Matrx Libra Fit Kit Compatibility & Versatility
The kit is fully compatible across all standard Matrx Libra Wheelchair Cushion sizes (from standard to heavy-duty bariatric models). It provides a flexible, re-usable solution for individuals with changing postural needs, progressive conditions, or specific orthopedic asymmetry.
