Using this mattress protector is easy. Just place it on your long single bed mattress, making sure the 50cm fitted skirt goes around the edges of the mattress to keep it in place. When it comes to cleaning, you can simply put it in the washing machine and then tumble dry it. It's important to follow the standard washing instructions to keep it in good condition. As it's treated to inhibit bacteria, fungi, and dust mites, you don't need to worry too much about these. But still, try to keep your bed area clean. In case you notice any damage, contact us within 5 years as it has a warranty for workmanship and faulty materials.
