Coastal 5-Piece Dining Set with Trestle Legs in Black / Poolside SlingTwo words can sum up the Coastal Collection: comfortable and carefree. Designed with materials that withstand all the elements, these dining chairs feature genuine POLYWOOD lumber frames and all weather sling seats with the perfect amount of bounce. While the versatile seats work with any and all style preferences, we love the look of the Coastal 5 Piece Dining Set, which pairs two armchairs and two benches with a rectangle dining table.
