When I stopped by the River West gallery/furniture showroom Caste (covered in our January/February 2008 issue) on a recent rainy afternoon, Ty Best, the artist behind most of the pieces in there, happened to be hanging out, working. He and co-owner Brad Rowley showed me these great new X-chairs, which called to mind African birthing chairs. The darker, faceted one is walnut that’s been treated with iron oxide to bring out the grain ($3,980) and the one joined by splines is Jamaican Blue Mahoe with a hand-rubbed wax finish ($3,770). The name of the store is Latin for “pure and clean,” not the repressive class system, and these sleek and surprisingly comfortable lounge chairs embody those ideals with aplomb.
