The most versatile JAY back for all shapes, sizes, and lifestyles

The JAY® J3™ backrest product line offers a multitude of width, height, and contour depth back shells to fit the back to the client. Each back is lightweight and adjustable, with numerous hardware choices allowing for easy installation.

NEW! CradleU Lateral and Whitmyer® Headrest Options
Designed for clients with postural or spinal deviations - including wider trunks and narrow hips, narrow trunks and wider hips, or curvatures - the NEW CradleU Lateral reshapes the existing contour of the off-the-shelf J3 back to match the client. The CradleU adjusts the contour by attaching directly to the J3 back shell beneath the foam, while the support plates adjust in angle to match the user's torso. The CradleU's intuitive design provides seamless support that minimizes interference with propulsion.

Also new to the J3 back are the Whitmyer Heads Up™ and Adjust-a-PLUSH headrest pads and LINX and ONYX headrest mounts!

Three Contour Depths
The Jay J3's solid shell is available in three contour depths to provide posterior and lateral pelvic and lateral thoracic stability to clients with varying postures and functional needs.

• Posterior - 2.2" of lateral thoracic support
• Posterior & Lateral - 3" of lateral thoracic support
• Posterior & Deep Lateral - 6" of lateral thoracic support
• Posterior & Deep Contour - 6" of lateral pelvic support

Four Support Height Levels
The JAY J3 back is available in four support height levels to provide support for clients with wide ranges of torso heights and levels of injury.

• Lower Thoracic - 6.5" to 9.5"
• Mid Thoracic - 12" to 15"
• Upper Thoracic - 16.5" to 19.5"
• Shoulder - 21" to 24"

The J3's hardware offers angle and width adjustability to improve visual orientation and function. Five options are available to accommodate a spectrum of client priorities and wheelchair configurations.

• 2-point (Standard or Extended) - easy to install, quick-release hardware that allows for numerous attaching positions
• 4-point (Standard or Extended) - quick-release hardware that withstands greater force by distributing across four mounting locations
• Lite Mount (pictured at right) - fixed hardware for a rigid mount that adds only .61 lbs.
