Overview of the Matrx PB Back

Invacare's Matrx PB Back is great for semi-active users and features Easy Set hardware for quick and easy installation and adjustments. The back has a standard 5" contour depth to provide midline support and positioning and it has a molded foam inner layer for comfort and protection.

What Makes This Different
The back shell of the Matrx PB is contoured, durable and lightweight. It also has a built-in plate for a headrest attachment. The outer cover on the shell and back is moisture resistant and breathable.

Why We Like It
An impressive selection of sizes and with several upgraded options make for a customized fit!  

What You Need to Know When Ordering
The Easy Set Hardware is standard and is easy to install and all adjustments can be made with the user in the chair. It is quick release and has infinite adjustments of depth, angle and rotation. It adjusts 2" behind and 2" in front of the back canes and it can be angled 20º posterior or anterior. The back can also be rotated to accommodate different pelvic and trunk positions. It fits 3/4", 7/8" and 1" diameter canes and an upgraded option is available for larger canes. The standard mounting pins allow the back to fit chairs that are 1" narrower or the same width and additional mounting hardware options are available for extended range, space saver needs and many other accommodations.
