Using this mattress topper is easy. Just place it on top of your queen - sized bed mattress. The deep - fitted walls will hold it in place. For cleaning, you can simply toss it in the washing machine. But make sure to follow the normal washing instructions on the care label. When it comes to maintenance, try to keep it dry and well - ventilated. Avoid exposing it to direct sunlight for long periods as this might fade the cotton cover. If you have any spills, clean them up promptly to keep the topper fresh and hygienic.
