Ladder-style backs give these HDPE stools more support than a plain perch, and the material handles weather without fading or cracking. Slats drain water and let air through, so a rain shower does not end the evening. Stainless steel screws resist rust, and soapy water is all the maintenance needed. Each stool carries 360 pounds with a 30-inch seat height. Recyclable material makes disposal easier down the line. Overall 24 by 18 by 48 inches; 31 pounds for the pair.
