The Rio R50 Outdoor Stacking Side Chair Set of 4 from Emu pulls up to one’s tables with a formal silhouette filled in with a relaxing grid design. The precise geometry at play here hints at the multi-faceted designer Gargano-Cristell’s love of shape. The stackable chair’s set of legs appears like a line drawing of an ASFORM steel tube construction. The legs produce tight, lovely curves that prop up the basket-like seat shell. A grid pattern of wires covers the chair’s interior for a cozy, airy backing. These wires sport cutting-edge welding that resists stress and rust. A powder-coated finish adds to the chair’s durability.
