Ombra means "shadow" in Catalan, perhaps an allusion to the functional ubiquity of RS Barcelona's well-conceived metal stool. Crafted in steel with a tough electro-coated finish in a range of smart polyester-paint hues, the stool from Emiliana Design Studio is sturdy, light and stackable. Generously sized with an ergomatically shaped seat, Ombra offers comfort either indoors or outside— wherever an extra seat is desired.
