The JAY J2 Plus Wheelchair Back is specifically designed to address the pelvic and trunk stability of bariatric users. It features an adjustable back width, to accommodate fluctuations in body width, and a bi-angular back, to maintain spinal contact and promote thoracic extension. The heat reducing design of the J2™ Plus Back lessens the effects of heat build-up and moisture, both of which leads to skin breakdown. A combination of slots in the shell and a special spacer-fabric lining in the cover promote the movement of air in and around the foam base.
