Invacare MPS Maxx Modular Power Standing System

Modular Power Standing System is available on the ROVI A3 and AVIVA FX base. Our innovative, highly adjustable MPS Maxx system combines a power standing function with a full range of power positioning options, all in a modular design that provides consumers with a unique combination of independence, function and accessibility.
In addition to the enhanced mobility and freedom offered by our MPS Maxx system, the medical benefits of adjusting to a standing position throughout the day are numerous, including better bone health, greater joint mobility, pain management, enhanced renal/bowel function and decreased risk for skin tissue breakdown.
