The inspiration for the Clamshell concept was found in the philosophy of architect Eero Saarinen: he believed that the most timeless and elegant furniture was a structural total and, absent excess decoration, the design could be reduced to its essence. From there, designer Craig Bassam pursued the clamshell shape for its purity of form and purpose. "The shell is so honest and beautiful in its own right. At the same time, it provides strength and support, without the need for frames or braces," says Bassam.

"I wanted to create a chair that meets prevailing notions of status and luxury," explains Bassam. "And I wanted an extremely comfortable chair." To achieve luxury and comfort without bulk, Clamshell employs an elegant structural shell made using advanced veneer technology. The shell's contour is based on compound curves found in nature that were impossible to express in wood—until recent advances in veneer molding. This breakthrough allows for shaping veneers without cracking, while maintaining the veneer's structure.
