Humanscale Diffrient World Chair Fabric Seat Description

Humanscale have developed the chair’s back using the laws of physics which eliminates the requirement for a separate lumbar support which tends to create a pressure point and requires manual adjustment. With patented Form Sensing Mesh Technology the backrest perfectly conforms to the sitter’s entire back as if custom made for them.

The Humanscale Diffrient World Task Chair Fabric Seat Black with its Invisible recline harnesses the user’s body weight to automatically provide the right amount of recline for every individual every time. Its groundbreaking mechanism-free recline action leverages two parts of the chair’s frame to provide automatic balanced support throughout the full range of motion for maximum support.
