Construction: Stevie's bases are sturdy all-weather powder-coated aluminum. Backs and arms use textured polyethylene synthetic wicker woven over aluminum pole framing. The tables, which are built into the seating pieces, are designer poly-wood. The cushions are made to the typical South Sea standard: Mold-and-mildew-resistant cores made from layered, high density polyfiber and dry conjugate blend, with covers sewn from fabrics of your choice. Each seat has independent vinyl-strapped suspension.
