A classic, modern design that enhances any environment, sculptor Harry Bertoia’s Diamond Lounge chair remains a fascinating study in bent metal and a fixture of mid-century design.The graceful Diamond Chair is an astounding study in space, form and function by one of the master sculptors of the last century. Like Saarinen and Mies, Bertoia found sublime grace in an industrial material, elevating it beyond its normal utility into a work of art.
