Using this Cool Gel Memory Foam Mattress Topper is a breeze. First, unpack it from its compressed packaging. Let it expand for 1 - 2 hours before you start using it, and for the best results, give it 24 hours to fully expand. Then, just place it on your Twin bed. When it comes to co-sleeping, you'll notice less motion transfer, so you and your partner can sleep undisturbed. To keep it in top shape, use a vacuum with a soft brush attachment to clean off any dirt regularly. Also, it's important to note that it's fire-rated according to 16 CFR 1303 and 16 CFR 1632, which adds an extra layer of safety. Enjoy a cool and comfortable sleep with this amazing mattress topper!
