Clinical Information

Utilising the multi-adjustable Easyset Hardware, the Matrx Posture Back Deep can be precisely positioned and orientated within the wheelchair for optimal postural support, and is easy to remove.

  • Provides excellent posterior pelvic support, helping to prevent posterior pelvic tilt and associated slouched posture
  • Full length lateral shaping for excellent postural guidance and support for passive users
  • Shorter backrest heights can be effective for active users, balancing the needs for postural stability and freedom of movement
  • Soft moulded foam insert for additional skin protection through maximised surface contact
  • The mounting pin design enables the backrest width to be prescribed to fit the individual, rather than the wheelchair, for optimal lateral support
  • Lumbar/PSIS pad supplied as standard
  • Headrest available as an accessory
  • Available in Heavy Duty and Bariatric size
