Poly~Wood is very proud of the comfort our new Nautical Collection provides. Each piece has been designed with contoured seating to provide proper support. Choose your desired back height in the Nautical Low Back or High Back Chairs, quickly becoming a favorite design.Poly-Wood®'s lumber is made from high-density polyethylene (HDPE), UV-inhibited pigment systems, foaming compounds, and selected process additives. The HDPE primary raw material is derived from post-consumer bottle waste, such as milk and detergent bottles or other HDPE post industrial material. This material is cleaned by a decontamination process to a high purity level, which removes contaminants such as food residue, paper, and adhesives. It is then compounded into a rigid board stock material; with the resulting finished product containing over 90% recycled plastic by weight.
