Humanscale Chairs & Stools

Humanscale chairs are always designed with user experience and product interaction in mind. The design team’s award-winning innovations for Humanscale's seating are backed by their thorough ergonomic research and consultations with specialists. Famous for the Freedom Task chair series, Niels Diffrient created the first Humanscale chair to self-adjust to each user's weight and frame. No need to turn knobs to get comfortable on the Humanscale office chairs for sale – just sit back and relax. His revolutionary idea continued on in the Diffrient SmartDiffrient World, and Liberty chairs, which all function according to the laws of gravity and automatically adjust and recline perfectly for each user.
