Our standard cushions (olefin and polyester) are water resistant but not waterproof so we recommend storing them in a dry place when not in use. The cushions from our Beach, Cordial, Dana, Rimini & Sorrento ranges are made using water resistant fabric and the fillings have a waterproof interliner around them so can withstand light showers and although the surface of the fabric will get wet, this will dry out quickly in the sun. We do recommend storing all cushions in a dry place during heavy rainfall and over winter. It is important to maintain your cushions correctly and dry them out if the insides do get wet. Remove the cover from the filling and dry out completely before using again.
