The Invacare Matrx Elite Deep 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 scapular cutout of the shell offers greater upper body range of movement making this back ideal for active users.    

The 6” contour depth provides higher lateral and trunk support and the removable lumbo-sacral support is easily adjustable to meet individual user needs. Visco or Super-Soft foam upgrades are available for added comfort and a more custom fit to contours of the body.

Standard, 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. Several no charge hardware options are also available to fit a wide variety of power and manual wheelchairs.

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 foam wheelchair back to meet your specific needs. See the Options tab above for more information.
