How does the AirFit™ BackRest work ?
The AirFit™ incorporates specialized Self-Inflating Technology (S.I.T.) into its design. S.I.T. to provide full adjustability for an individualized level of support to the curve (lordosis) of the low back. The outer shell of the AirFit™ is constructed of an impermeable, durable, and non-slip fabric. Internally the AirFit™ contains polyurethane foam that expands when the valve is open, and can then be compressed to provide a user determined level of firmness . The patented easy twist valve controls the air flow so the user can select just the right amount of firmness making the AirFit™ comfortable, adjustable, and portable too. The AirFit™ fills in the space between the lower back and the chair. This supports the natural curve of the spine, and promotes a natural forward tilting of the pelvis – supporting the spine in a more healthy and natural alignment (good posture) when sitting.
