Spine-Align: Let the Back Fit the User

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.
