Info
With the backrest, the Humanscale Liberty mesh has a combination of three panels of non-stretch materials to follow the natural contour of the user's back to provide a personalised fit and support the user through the working hours.
The Liberty Task Chair features the same principles as Humanscale's most popular products: to make the chair simple and efficient to set up, achieving the optimal comfort the user needs. The unique mechanism-free recline function uses the sitter's weight to automatically obtain the perfect support; the user is encouraged to move and change posture without any restrictions of manual controls.
The Humanscale Liberty also features:
Counter-balance recline mechanism that provides the right tension and support when the user is reclined with no tension dial or recline lock.
Contour seat cushion to reduce pressure from the legs
