Tati's design scheme of a simple outlined tabletop set in a curvilinear metal frame gets the luxe treatment in this rich limestone version. Designer duo Johan Ridderstråle and Mats Broberg's square coffee table comes in 2 heights—and the slightly narrower lower model can slide into the taller one to be used in tandem. Surfaced in either solid Belgian or Jura Grey limestone, the distinctive powder-coated structure is available in a full range of neutral and accent hues.
