The Humanscale® Liberty™ Office Chair has a tri-panel, non-stretch construction that "senses" your form, creating body-fitting contours with appropriate lumbar support. The stretch provided by the mesh back of Humanscale Liberty Chair adjusts to your body for ultimate comfort.
Plus, the Liberty™ office chair has only 2 manual controls. It makes the other adjustments itself so that you don’t have to.
Humanscale Liberty Office Chairs' patented, “intelligent” counter-balance mechanism automatically provides the proper amount of recline tension for your body size and weight.
And the pivoting backrest adjusts automatically to the changing needs of your spine as you go through your day.
