The Humanscale Liberty chair with height adjustable Headrest features a revolutionary counter-balance mechanism, based around movement. Your body weight automatically balances the force required to recline the chair. So the recline tension is always perfectly adjusted to let you move while keeping you fully supported in all positions. The Liberty chair features a height adjustable back rest, height adjustable headrest and a seat with built in seat slide to adjust the seat depth.

The Chair features weight-sensitive recline and synchronously adjustable armrests which keep the sitter exceptionally comfortable while also lowering the risk of long-term injury.

Finished in Metropolis Wool, Zone Vinyl or Pucinni Leather.

Features

1) Automatic Headrest
Freedom’s dynamic, position sensitive headrest adjusts to cradle your head and neck as your recline, and moves out of the way when you sit upright automatically.

2) Recline Action
As you recline, you’ll maintain a near consistent eye level, while the angle between your torso and legs opens up for better body function.

3) Contoured Cushions
The cushions are sculpted to closely follow body contours, which increase contact and decreases concentrated loads. Our optional Technogel® seat cushion maximizes weight distribution and comfort.

4) Responsive Backrest
The pivoting backrest automatically adapts to the changing needs of your spine during recline.

5) Synchronous Armrests
Freedom’s body-friendly gel armrests move up and down together and stay with you during recline, always keeping you in supported balance.

6) Body Fit
The seat, backrest and headrest may be independently positioned to fit your exact body size.

7) Intelligent Mechanism
With Freedom’s revolutionary counter-balance mechanism, your weight automatically balances the force required to recline the chair. So whether you’re big or small, short or tall, the recline tension is always perfectly adjusted to let you move while keeping you fully supported in all positions.
