Using your new king-sized gel-infused memory foam mattress topper is a piece of cake. First, take it out of the box and unroll it on your mattress. Since it comes compressed, give it 48 to 72 hours to fully expand. Once it's all puffed up, you're ready to enjoy a great night's sleep. When it comes to maintenance, just spot clean it if there are any stains. Avoid using harsh chemicals as they might damage the memory foam. Also, try to keep it away from sharp objects to prevent tears. If you want to make the most of the five-zone support, just lie down as you normally would, and the topper will adjust to your body shape. And remember, the cooling gel will keep you cool throughout the night, so you can sleep in comfort.
