Yes, you should still use garden furniture covers even if your furniture is made from wood. Even treated hardwood garden furniture, including teak, acacia and eucalyptus, can be affected by prolonged exposure to moisture, UV rays and changing weather conditions, which may lead to fading, cracking, warping or mould and mildew growth. A suitable garden furniture cover also helps protect wooden furniture from dirt, pollen, bird droppings and fallen leaves, reducing cleaning and helping to keep it looking its best for longer.
