Mixing pieces from different periods gives this sitting area a lively vibe. A vintage midcentury armchair in cool gray has clean, straight lines. The dresser was rescued from an old barn and spruced up with a coat of black lacquer. Blue walls are striking, but the cool tone keeps the vibe calm. A scallop-pattern rug, diamond-embossed side table, and World Bazaar-inspired pillow keep the eclectic mix going.
