Humanscale Diffrient Smart Chair

item#: HUS906

Neils Diffrient, legendary chair designer, set out to design an office chair equally suited to the conference room, the board room and the break room. The result is the Humanscale Diffrient Smart Chair. More than mere chair, this is an intuitive seating system that requires very few manual adjustments. Its weight-sensitive reclining mechanism was developed to react to individual bodies and seated postures, and its form-sensing three-panel mesh offers excellent support. Enjoy the distinctive look and feel of the Humanscale Diffrient Smart Chair. Humanscale chairs are Manufactured in the USA.

    Fabric - Grade 3


    Sensuede was developed to be the best and most luxurious engineered suede available. The faux suede's soft touch comes from the use of breathable and wrinkle resistant recycled microfibers that are finer than a human hair but are extra-strong, resulting in a very resilient fabric. This material also was selected because of its environmentally sensitive content and manufacturing process.
