Latex is a naturally derived biodegradable product and comes from a rubber tree. It breathes to keep you warm in winter and cool in summer. Bacteria, mildew, mold and dust mites cannot live in latex foam making it an excellent choice for those who suffer from the allergies as well as anyone who wants a great nights sleep! Latex will naturally adjust to the contours of your body to provide gentle orthopedic support and we offer a variety of firmnesses to choose from.
