The Unica Tables are crafted in solid American black walnut hardwood with natural finish or solid cherry hardwood in five finishes* or solid ash hardwood with three finishes*. The tables in walnut are finished with a low sheen (10 sheen) top coat. *Natural variations in solid wood and hand-applied finishes make each piece unique. Slight grain and finish irregularities as well as subtle differences in stain shades are signs that the furniture has been crafted from solid wood and are considered hallmarks of quality. Conventional finish is now GREENGUARD Certified for low chemical emissions.
