Porch wicker is made of natural materials. Due to the properties of the material and the manufacturing and finishing process it is suitable for limited outdoor exposure. Limited outdoor exposure refers to outdoor use, but on a covered porch. Occasional weather is fine, as long as the furniture is not directly exposed to the sun and rain. Product will still naturally weather outdoors, including frame colors, and binding. This is a normal outcome of using natural furniture in outdoor environments.
Porch wicker, of course, is perfect for indoor use as well.
