Berlin Gardens furniture is crafted using only the very highest grade of poly lumber (High Density Polyethylene). The density and smoothness of Berlin Gardens furniture is far superior than that of similar brands due to the extremely high quality control standards and special agreements between Berlin Gardens and its suppliers. This means no voids on the cut edges or rough, discolored surfaces on your fine piece of furniture. Made of nearly 100% recycled milk jugs, poly lumber offers many advantages over other materials used in outdoor furniture. It's ecologically responsible, easy to care for, and needs no painting or indoor storage. Poly lumber will not crack, splinter or support bacterial growth. It remains unaffected by salt spray. The color is not a coating - it goes all the way through the material and is UV stabilized to resist fading.
