While urethane foam lumbar supports can feel hard and are only available in one durometer, Inertia Lumbar Support can be inflated to create a more supportive curvature – or deflated to provide only the support the user requires.

Step 1

To increase the curvature of the lumbar support, squeeze the hand pump several times until the desired air pressure is reached.

Step 2

To minimize the curvature, simply press the release valve to the desired pressure.

Step 4

When Inertia Lumbar Support is specified with our BHA (Back Height Adjustment) option, both the lumbar depth and height can be precisely positioned to best support the user.
