Described by The New York Times as "the gold standard in office seating," the Freedom chair redefines the concept of traditional task chairs. Designer Niels Diffrient aimed to design an office chair that automatically adapts to the user, allowing them to move freely from posture to posture. Diffrient’s unique approach removed complexities found in other chairs, such as cumbersome recline levers and back tension dials for a truly ergonomic task chair. As a result, he developed a recline mechanism that perfectly adjusts to the user, definitively reinventing modern task seating to be truly simple, functional and beautiful.

Any fixed posture, no matter how closely it approaches the optimal, will generate muscle fatigue. Therefore, it is important to build in flexibility to allow operators to shift positions easily.

Relax. It's good for you
An upright sitting posture transfers the weight of your entire upper body through your spine directly to the sitting bones, increasing pressure and discomfort. Reclining, on the other hand, transfers some of the body's weight to the backrest, reducing the load on your sitting bones. The more you recline, the more the weight of your body is proportionately distributed. Also, the angle between your torso and thighs opens up, allowing better breathing and easing internal pressure. This is why you can stay fully recumbent for hours without discomfort.

Perfectly adjusted recline
Liberty's revolutionary exoskeletal design works like a humansized weighing scale. The chair's virtual pivot point is at the body's natural pivot point - the hip - so the geometry of the chair parallels that of the body. As you recline, your weight automatically balances the force required to recline the chair, effortlessly keeping Liberty in perfect balance with you. That's why you're fully supported at all times without the need for locks.

Infinite Tilt
The optional Infinite Tilt mechanism allows you to tilt the entire chair 6° forward or 5° further to the rear. Forward tilt of the entire seat pan rotates the pelvis and puts the lumbar area of the spine into a healthy lordotic curve preferred for desktop work. In forward tilt, the backrest follows the tilt of the seat to provide constant back support. The additional tilt toward the rear gives the whole chair an exceptional 27° of recline - far more than the other leading office chairs.

Armrests matter
Armrests are critical to long-term comfort and health. Without them, the neck and shoulders have to carry the weight of the arms (11% of body weight), putting strain on the upper back and pressure on the spine. But incorrectly adjusted armrests cause similar problems. Different tasks require different armrest heights: low for desk work and keyboarding/mousing, mid-range for conversational posture, high for reading/reclining. If armrests are not adjusted as tasks change, then the user isn't getting their full benefit.

Synchronous is easy
The revolutionary armrests on Liberty, with a vertical range of 178mm/7", can be adjusted synchronously without release buttons. In fact they're so easy to use that people will actually adjust them throughout the day to correctly support their many different tasks. The Environmental Story
