This all-weather ottoman is designed to be used with or without a cushion. The frame is designed to resemble hand-made birch furniture with a complementary weave. Frame: sturdy, maintenance-free, non-corrosive aluminum with powder coat finish. Faux birch: 100% HDPE (High Density Polyethylene) infused with UV inhibitors. Cushions: 100% Sunbrella® Acrylic fabric. Cushion fill: 100% engineered polyester fiber. Frame: clean with mild soap and water, rinse clean and allow to dry. Cushions: vacuum regularly to remove unseen organic debris that allows mildew to grow. Acrylic cushions can be cleaned using a soft bristle brush with cold water and a mild chlorine bleach solution. After cleaning, rinse thoroughly and allow to dry. If desired, apply a new coat of Scotchgard™ or other premium fabric protector. All-weather faux birch has a natural "give" for total body comfort. Most cushions are reversible. Cushion fill is water-resistant and has excellent drainage and resiliency. Manufactured to be used in any outdoor environment. Faux birch is scratch resistant, will not rot, peel, fade, or chip and is UV protected. Dimensions: 35" W x 25" D x 18" H. Weight: 40 lb.
