Each strand of resin wicker is hand woven over aluminum frames. Many lesser competitors use steel frames that will rust. The resin wicker material is made from high density polyethylene, proven to last for years in outdoor exposure. Two fiberglass springs attached to an all aluminum swivel mechanism provides a smooth rocking motion, and aluminum doesn't rust. Only stainless steel fasteners are used where movement is desired. These won't rust or become wobbly with other fasteners.
