The most versatile JAY wheelchair backrest!
The JAY® J3® wheelchair back range offers a multitude of different widths, heights, and contoured depth back shells to suit the clients individual positional needs. Each backrest is lightweight and adjustable, with numerous hardware choices allowing for easy installation.

Five Contour Shapes
The Jay J3's solid shell is available in five contour shapes to provide posterior and lateral pelvic and lateral thoracic stability to wheelchair clients with varying postures and functional needs.
- Posterior (PA) - 2.2" of lateral thoracic support
- Posterior Lateral (PL) - 3" of lateral thoracic support
- Posterior Deep (PD) - 6" of lateral support
- Posterior Deep Lateral (PDL) - 6" of lateral thoracic support
- Posterior Deep Contour (PDC) - 6" of lateral pelvic support

J3 Plus for Bariatric Users
Designed to specifically address the pelvic and trunk stability needs of the bariatric client, the new J3 Plus Backrest* features an optional lower vanity shell extension that can pivot to accommodate redundant tissues, allowing proper positioning without interference. Accommodating up to 226kg. in widths of up to 26", the J3 Plus Backs are available with either TH 2-point or FS 4-point hardware and features a 2.2" deep contour to provide for non-restricted movement.

Four Hardware Options
The J3 Backrest offers four hardware options to accommodate a span of priorities and wheelchair configurations.
- SH: Easy to install, 2-point, quick-release hardware that allows for numerous attaching positions
- RH: 25% lighter than SH hardware and optimized for ultra lightweight wheelchairs without compromising adjustability
- TH: 2-point, quick-release hardware optimized for tilt-in-space wheelchairs, with a lengthened attachment pin and 226kgs weight capacity
- 4-Point: Quick-release hardware that withstands greater force by distributing across four mounting locations

Spine-Align: Let the Back Fit the User
Fitting the back to the user not the user to the back is the goal of the Spine-Align Posture Conforming system. This is accomplished by combining a wide range of individual foam components to create unique shapes that optimize postural support, evenly distribute pressure, and maximize function. Velcro strips attach to each shape so they can be placed into hundreds of configurations. The flexibility of the system is boundless.
