This simpe, attractive Rounded Edges Chair is by Montreal-based industrial designer David Raymond. It's made of three 1/4"-thick aluminum pieces that are riveted together.
It's funny what a difference color makes; I find the pale green version striking, while the natural aluminum version leaves me a bit cold.
Raymond opened his studio, LESORR (Les Objets Raymond Raymond) just last year. He's self-producing the Rounded Edges Chair, making them to order.
