Poly is a popular material used for patio furniture. Specifically, poly is a heavy-duty, recycled, and all weather plastic material that is formed into wood-like lumber during the manufacturing process. Poly furniture goes by many different names. You'll hear poly furniture referred to as: faux wood, polywood, trex, wood look, poly resin, composite, polyethylene, HDPE, poly plastic, recycled plastic, all weather, & weather resistant patio furniture.   Those synonyms are all generally used interchangeably. Technically speaking, however, there are slight differences in the materials listed above - and it all depends on the individual seller.   Phat Tommy's proprietary poly outdoor furniture is made from 100% recyclable polyethylene plastic. This heavy-duty plastic is also referred to as High-density Polyethylene (HDPE). HDPE material is equally strong, weatherproof, and comfortable - making it the best all weather patio furniture.
