This outdoor bench is constructed of genuine POLYWOOD lumber, a proprietary blend made from sustainable materials, including landfill-bound and ocean-bound plastics. Resistant to moisture, stains, and fading, POLYWOOD furniture is built to withstand a range of climates including hot sun, snowy winters, and strong coastal winds. The durable, low-maintenance HDPE frame won't crack, peel, chip, or splinter, and it never needs to be painted, stained, or waterproofed. This furniture cleans easily with soapy water and a soft-bristle brush. Assembles easily with clear instructions, and marine-grade quality hardware is included. POLYWOOD furniture is made in the USA and comes with a 20-year limited residential and 3-year limited commercial warranty.
