Matrx MX2 Back with Fixed Mount Hardware Buyer’s Guide
The Matrx MX2 Back with Fixed Mount Hardware by Motion Concepts is an ultra-lightweight carbon fiber wheelchair backrest engineered specifically for active manual wheelchair users. Combining precise ergonomic support, exceptional aesthetics, and permanent structural rigidity, this fixed-mount system maximizes energy transfer and propulsion efficiency without adding unnecessary weight to the chair frame.
Ultra-Lightweight Carbon Fiber Construction
The Matrx MX2 features a solid carbon fiber shell designed to offer maximum strength while keeping total product weight to an absolute minimum (starting under 1.5 lbs). The lightweight build reduces overall chair weight, significantly decreasing shoulder strain and fatigue during daily manual propulsion.
Matrx MX2 Back Weight Capacity
Engineered with high-tensile carbon fiber and durable hardware components, the Matrx MX2 backrest comfortably supports active users up to 250 lbs. The rigid carbon structure ensures no flex under pressure, delivering steady trunk stability and efficient energy output per push.
Streamlined Fixed Mount Hardware
This model comes equipped with low-profile Fixed Mount hardware, providing a solid, non-removable connection to the wheelchair's back canes. The fixed bracket design preserves seat depth, eliminates play or rattle over time, and offers an ultra-clean look ideal for rigid frame manual chairs.
Anatomical Contours & Sacral Cutout
Offered in 3-inch active positioning contour depths, the shell shape provides effective lateral trunk stability without restricting upper body rotation or arm movement. An integrated sacral notch prevents sacral pressure and allows natural pelvic tilt for optimal spinal alignment.
Breathable Spacetex Outer Cover
The system is wrapped in a high-performance Spacetex outer cover paired with high-resilience foam padding. The multi-stretch fabric promotes continuous airflow, manages temperature and moisture buildup, and shields sensitive skin from friction and shear forces.
Adjustable Lumbar Support Pad
Included with the backrest is a removable, positional lumbar pad that fits behind the foam layer. This allows users to fine-tune lower back and pelvic support to tailor the depth and curvature to their specific spinal alignment needs.
Precision Height and Angle Tuning
Even with permanent fixed mounting hardware, the slotted back shell enables precise adjustments for height, depth, and back angle orientation (up to 30° range). Users and clinicians can tailor position settings during fitting to maximize dynamic balance and trunk control.
