This cool new Concrete Slab Coffee Table is a blend of rustic, modern, and industrial design all fused into one tough and unique indoor / outdoor coffee table. The tabletop slab is constructed from hand-poured all-weather concrete composite that is hand-buffed and sealed and rests upon a kiln-dried teak wood base with a weathered finish. Hmm, it looks super durable, but you should probably still use a coaster... a concrete one.
