This cushion attaches to the Grade A Teak Adirondack Ottoman with discreet velcro fasteners for a secure, tailored fit. The supportive foam core is wrapped in machine-washable Sunbrella® fabric—the leader in performance textiles. Made to withstand rain, snow, mold, and mildew, it's also made with UV-stabilized pigments and solution-dyed acrylic fibers for exceptional fade resistance over time.
