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 optimise postural support, evenly distribute pressure, and maximise function. Velcro strips attach to each shape so they can be placed into hundreds of configurations. The flexibility of the system is boundless.
