Humanscale’s Diffrient World chair is made from eight major parts and weighs less than 25 pounds (11 kg), meaning it requires less raw material and fewer manufacturing processes than other chairs. The chair features form-sensing mesh technology to ensure lumbar support and its mesh seat pan with a frameless front edge provides all-day comfort. At the end of its life, 95 percent of its components can be recycled.
