Matrx PB Standard Back Buyer’s Guide
The Matrx PB Standard Back by Motion Concepts is a lightweight, high-performance wheelchair positioning backrest designed to deliver optimal pelvic and lumbar support. Featuring a pre-formed contoured shell with a 5-inch depth contour, it provides gentle lateral stability, proper spinal alignment, and maximum upper-body freedom for active wheelchair users.
Pelvic and Lumbar Posture Alignment
The Matrx PB (Posture Back) is anatomically contoured to support the natural curve of the lumbar spine while stabilizing the pelvis. Its structured design prevents posterior pelvic tilt and sacral sitting, reducing fatigue and promoting a healthier upright posture throughout the day.
Matrx PB Standard Back Weight Capacity
Engineered with a light yet durable aluminum shell, this backrest supports users up to 300 lbs (standard sizes) or up to 500 lbs (heavy-duty version). The rigid back structure ensures consistent, non-flexing trunk stability without adding unnecessary weight to the wheelchair frame.
Anatomical 5-Inch Contour Depth
Featuring a built-in 5-inch lateral contour depth, the backrest offers moderate side-to-side trunk support without feeling restrictive. The tapered shape accommodates dynamic movement and unhindered arm function, making it ideal for self-propelling manual wheelchair users.
Matrx PB Quick-Release Mounting Hardware
Outfitted with EasySet or Pin-Style mounting hardware, the backrest allows rapid, tool-free removal for easy transport and folding. The hardware provides independent adjustment of depth, angle, rotation, and height to ensure a precise, customized fit while the user remains in the chair.
Moisture-Wicking Breathable Cover System
The backrest comes equipped with an oversized HR foam cushion wrapped in a moisture-resistant, breathable SuperSoft outer cover. This advanced cover fabric manages heat and humidity buildup, reduces skin shear forces, and wipes clean easily for hassle-free maintenance.
Adjustable Lumbar Support Pad
Included with the backrest is a removable foam lumbar pad that can be repositioned inside the cover to customize lower back support. It enables clinicians and users to fine-tune sacral prominence and lumbar lordosis support based on individual comfort needs.
Integrated Headrest & Lateral Accessory Compatibility
Designed for comprehensive positioning customization, the back shell features pre-drilled mounting holes for headrests and swing-away lateral supports. This allows easy integration of secondary positioning accessories without compromising the back shell's structural integrity.
Matrx PB Standard Back Review
The Matrx PB Standard Back by Motion Concepts is an exceptional daily positioning solution for wheelchair users seeking reliable pelvic control and lateral support. Combining quick-release hardware, customizable lumbar padding, and a lightweight contoured design, it provides an ideal balance of ergonomic comfort, posture correction, and everyday function.
