Matrx PB Extra Wide Heavy Duty Back Buyer’s Guide
The Matrx PB Extra Wide Heavy Duty Back by Motion Concepts is a bariatric wheelchair positioning backrest specifically engineered to fit wider seat frames while delivering robust postural support. Built with a reinforced heavy-duty shell and molded high-resilience foam, it offers optimal trunk stabilization, pelvic positioning, and long-term durability for bariatric users requiring extended-width back support.
Extra-Wide Bariatric Frame Compatibility
The Matrx PB Extra Wide Heavy Duty Back is tailored specifically to fit larger manual and power wheelchair seat frames ranging from 25 to 30 inches wide. Its expanded structure allows bariatric users to achieve precise midline support and positioning without sacrificing space or lateral comfort.
Matrx PB Extra Wide Heavy Duty Weight Capacity
Engineered for heavy-duty load demands, this backrest comfortably supports weight capacities up to 500 lbs. Its reinforced composite and aluminum structure prevents shell deformation or flexing under pressure, maintaining consistent spinal alignment and sacral stability during continuous use.
Anatomical Contours & Postural Alignment
Featuring standard 5-inch contour depth (or available 7-inch deep contours), the back shell wraps around the trunk to provide stable lateral support and midline guidance. This design helps maintain an upright seating posture, preventing lateral leaning while ensuring freedom of upper-body movement.
Heavy-Duty EasySet Mounting Hardware

Adjustments can be made quickly while the user remains in the wheelchair, making initial setup and ongoing fitting effortless for clinicians and caregivers.
Moisture-Resistant Upholstery & Breathable Cover
The backrest comes covered in a durable, moisture-resistant outer upholstery layered over molded Ultra-Fresh™ high-resilience polyurethane foam. The breathable fabric reduces heat and moisture accumulation, protecting skin integrity and minimizing shear forces during extended periods of sitting.
Customizable Lumbar & Sacral Support
Included with the backrest is a removable, positionable foam lumbar pad that allows users and therapists to tailor lower back support. Adjusting the lumbar insert helps promote natural spinal curvature, reduce lower back fatigue, and prevent slouching.
Integrated Headrest Mounting Adaptability
