Poly or recycled plastic makes great outdoor furniture because it is durable, virtually maintenance free, and environmentally friendly. Poly stands for polyethylene which is the most common form of plastic. It is made from milk jugs, detergent bottles and more, and when used for outdoor furniture, plastic is being kept out of landfills. Another benefit is there are no harsh chemicals needed to keep your poly furniture clean, just soap and water. Poly comes in many shapes, sizes, and colors perfect for any setting.
