Cover or store indoors during inclement weather and when not in use to prolong the lifetime of your furniture. Use a proper outdoor cover (not included) that allows for adequate ventilation without trapping moisture. Do not leave uncovered in direct sunlight for extended periods of time. Left unprotected, teak especially will weather and lighten in color. Dust regularly with a clean, dry cloth. Avoid ammonia-based cleaners or other chemicals. Sunbrella high-performance cushion covers are made of 100% solution dyed acrylic fabric and an open cell foam designed specifically for outdoor usage. Seat covers are fade resistant and easily cleaned with soap and water.
