The Tivoli Collection pairs Artisan craftsmanship with a heavyweight sand and cast aluminum frame, designed to be one of our sturdiest sets. Each piece in this 11 piece combo dining set features a sleek matte black finish, enhanced with weather-resistant properties such as a UV-resistant and electrostatically applied powder-coat. The dining chairs and swivel rockers have a sand and die-cast aluminum frame that is crafted with a lattice design on the back and seat. As an easy storage benefit, this dining chair stacks, so you can always maximize your outdoor space regardless of how many guests you're entertaining. The 71-103 x 44 in. double extension dining table features a basketweave tabletop design with a decorative trim surrounding the legs. Two extensions are included which will increase the overall length to 103 in. allowing you to seat 10 -12 persons comfortably dependent upon your chair dimensions.
