You've designed your ideal table, from top to bottom in just the right size. The warm grey concrete top is a mix of marble, stone and granite powders with natural fibers for added strength. This industrial, modern surface is handmade in an eco-friendly shop powered without fossil fuels. Due to the handmade nature of the concrete mix, color will vary and may change over time. The traditional Parsons-style base is a hot-rolled steel frame that supports with clean simple lines, hand-welded and ground at each corner with a raw, torched millscale finish. The Parsons Concrete Top/ Dark Steel Base Dining Tables are Crate and Barrel exclusives.
