Humanscale

Humanscale is best known for its Freedom chair, which was designed by Niels Diffrient and introduced in 1999. The chair was considered revolutionary for its internal counterbalance mechanism that supports the user’s body at all points during recline, a first for task chairs. The Freedom chair's other unique feature is its patented synchronous arms, which adjust simultaneously. Humanscale’s other notable task chair is its Liberty chair, also designed by Niels Diffrient, which was introduced in 2004. The Liberty chair features a tri-panel mesh back designed to provide lumbar support. Like the Freedom chair, Liberty is also outfitted with a balanced recline mechanism that is designed to support all sitters throughout recline. Humanscale also manufactures keyboard support systems, monitor arms, task lighting, and various other ergonomic work tools.
