The Rio R50 Outdoor Stacking Armchair from emu adds an enduring retro expressiveness to outside spaces. Designed by Emanuel Gargano and Anton Cristell and stackable up to eight chairs at a time, its slim bracket-style legs of steel provide both lightness and style, offering resistance to inclement weather. A grid-style seat and back of slender metal strands provide ample support and can easily retain any cushions that are compatible to add.
