The Golden Gate bridge provided the inspiration behind fuseproject's new SAYL chair for Herman Miller—its unique, frameless back mimics the tectonics of suspension bridges, providing ergonomic support with no hard edges. Though prototyping began in wood and rope, the trademarked "3D Intelligent Suspension Back" is enabled by a proprietary urethane and two additional trademarked inventions: the ArcSpan&tm; seat base and the Y-Tower&tm; suspension structure. Both elements assist in holding the urethane sheet in tension.
According to Herman Miller, this structure creates a chair that is fully supportive—with a thickening and hinging of the urethane sheet in the sacral, lumber and spine areas— but also flexible, responding to the movement of the chair's occupant.
