The Seascape M82014 Bar Height Stool has an aluminum frame with HDPE (high-density polyethylene) lumber for the seat. HDPE material is made from post-consumer bottle waste such as milk jugs and detergent bottles, making this an environmentally friendly product. The Seascape M82014 is a transitional design and is available in any Texacraft powder coat finish to coordinate with any one of 4 lumber colors to select from. Optional seat pads are sold separately. The pads add additional comfort and a splash of color to the chair.
