Using this mattress topper is a breeze. First, unpack it. It comes compressed for easy transport. Let it expand for 1 - 2 hours before you use it, and for the best results, wait 24 hours for maximum expansion. Then, just place it on your full-sized bed. When it comes to co-sleeping, you'll love how it reduces motion transfer, so you won't be bothered by your partner's movements. To keep it in good condition, clean it regularly with a vacuum cleaner that has a soft brush attachment. This will help remove dust and keep it fresh. Also, it helps prevent the growth of airborne irritants, but make sure to keep your bedroom well - ventilated for an even healthier sleeping environment. Enjoy the cooling sensation all night long and have a great sleep!
