The Clamshell Chair achieves luxury and comfort without bulk through its elegant structural shell. Geiger’s advanced veneer technology allows Clamshell its curves, a shape beautiful on its own that also provides strength and support without need of a standard frame. With a five-star, height-adjustable swivel base on casters, it can be used as a desk chair or conference chair.

Design Story

In designing their Clamshell family of seating, Craig Bassam and Scott Fellows were inspired by the philosophy of Eero Saarinen, who believed that the most timeless and elegant furniture is a structural whole that, absent excess decoration, can be reduced to its essence.
