The mattress that breathes!  The Air20 is our most popular mattress for a host of reasons. Being too hot in the night can make you sweaty and uncomfortable, causing you to toss and turn in your sleep. And that can disturb not just you, but your partner too. As you move, the unique spring construction of the Air20 actually pumps air around the mattress and through the foam matrix surface. Thermal testing of the Air20 proves that after just 15 minutes of contact with the surface, pockets of cold air start to regulate the user’s temperature — meaning you can change positions easily without becoming too hot or sweaty as you sleep. Because its structure provides unparalleled ventilation and a cooler, drier environment, the Air20 is also inhospitable to allergens and dust mites – a common problem with mattresses the world over. Meaning less allergies, and a more refreshing sleep!
