Are the FC furniture covers waterproof?

No. Our furniture covers are designed to protect your garden furniture from atmospheric dust and dirt. The covers are made from Polyester which is breathable, allowing air to circulate around the furniture when covered. If they were 100% waterproof, moisture would get trapped between the cover and the furniture encouraging mould and mildew. We would suggest placing a bucket upside down on your table, or leaving the bottom pole of your parasol in the table to create a tent effect. This allows rain water to run off and prevents water pooling on the cover.
