JAY (Sunrise Medical) · Rigid backrests · AC-046
The JAY J3 Back is a modular rigid wheelchair backrest from Sunrise Medical, offered in a wide grid of sizes. Twelve heights span four support levels, from lower thoracic at 6.5 inches to shoulder height at 24 inches, and contour depths of 2.2, 3 or 6 inches set how much the shell wraps the trunk. The lightest shells weigh from 1.4 lb without hardware. Mounting hardware allows 20 degrees of angle adjustment.
Covers a broad range of users, from active people who want a low back at lower-thoracic level to those who need shoulder-height postural support with deep lateral contour. Height and contour are normally chosen with a seating clinician.
