Chess can be such serious business. Designer Adin Mumma puts the fun into the game with a new set for Umbra’s U+ Studio Collection. Combining a topographical board featuring concave squares with minimalist playing pieces that have rounded nickel bases, the Wobble chess set adds a kinetic element to a contemplative pursuit. Made from maple and walnut, it’s a handsome, sculptural addition to any game room, intriguing children and design-savvy adults. It’s $290 at Colcha, 1416 Abbot Kinney Blvd., Venice; (310) 392-3600; www.colchahome.com.
