Humanscale chairs are always designed with user experience and product interaction in mind. The design team’s award-winning innovations 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 users weight and frame. No need to turn knobs and fit these conference chairs or computer chairs for sale, just sit back and relax. His revolutionary idea continued on in the Diffrient Smart, Diffrient World, and Liberty chairs, which all function according to the laws of gravity and automatically adjust and recline perfectly for each user.
