Caring for Wicker Furniture
Wicker refers to the plaited fibers, such as pliable reeds and branches, grasses, plastic strands and other sources woven into furniture or baskets, rather than a specific product or plant used to make these items. Resin wicker furniture -- designed for outdoor use or patio furniture -- holds up to the elements better than wicker made from natural materials. Sometimes called outdoor wicker or all-weather wicker, resin wicker's actual composition varies from brand to brand. Made from a synthetic extruded material similar to plastic, resin wicker can last for many years compared to wicker made from natural fibers.
