It took Béhar and Herman Miller two and a half years to perfect the chair, which employs a novel "3D Intelligent Suspension Back" instead of a traditional frame. A special new type of urethane is used for the frameless back, which is injection-moulded with different degrees of tension for the various areas of the back and is held in place by a new Y-Tower suspension tower.
The novel suspended structure not only allows for a comfortable, ergonomic sitting experience but also greatly reduces the materials needed to produce the chair, in turn lessening its overall environmental impact. 93 per cent of the Sayl's materials are recyclable. If you're interested in introducing your butt to a host of new innovations in chair engineering, the Sayl is available in a variety of colours and finishes over at Herman Miller.
