Using your new mattress protector is a breeze. Just place it over your king single bed mattress, making sure the 50cm fitted skirt wraps around the mattress snugly. You can sleep on it right away and enjoy a cool and clean sleep environment. When it comes to cleaning, simply toss it in the washing machine and then you can tumble - dry it. But remember, use a gentle cycle to keep it in good shape. To maintain its performance, avoid using harsh chemicals. Thanks to the Ultra - fresh treatment, it helps keep bacteria and mites at bay. If you ever notice any issues with workmanship or materials within 5 years, you can rely on the warranty.
