The Invacare Elite Heavy Duty Wheelchair Back features a lightweight, slightly contoured aluminum shell with molded foam that wraps around the shell for maximum comfort and midline support and positioning. The 500 pound weight capacity makes this wheelchair backrest ideal for larger users and the scapular cutout of the shell offers greater upper body range of movement.  

The 3” contour depth provides positioning support while maintaining range of motion and the removable lumbo-sacral support is easily adjustable to meet individual user needs. Optional fixed lateral pads provide optimal trunk support.

Heavy-duty, quick-release, Easy Set hardware makes installation and removal of the back a breeze and allows for quick adjustments in depth (4”) and angle (40°) while the user is still in the wheelchair. 

The outer cover of this foam wheelchair back wraps around the entire back and is made from Meshtex fabric that helps wick away moisture and heat to keep you cool and dry.

Other options and accessories including a privacy flap, wipeable slipcover and military service emblems are available so you can build your Elite Heavy Duty foam wheelchair back to meet your specific needs. See the Options tab above for more information.
