You want your sleeping surface to be as non-toxic as possible. Unfortunately, conventionally-made mattresses contain synthetic materials, like polyurethane foam, that can release volatile organic compounds (VOCs) into the air—and your lungs!—and cause adverse skin reactions and breathing problems, experts say. When it comes to looking for a natural, long-lasting alternative, latex may be your best option.

Look for a hybrid mattress made with inner coils and certified organic Dunlop latex harvested from trees. It’s free from synthetic foams, chemical adhesives, and chemical fire retardants (their fire retardant is made from silica and better for your health). Plus, the top layer of the mattress that’s closest to your body is made from certified organic cotton and wool. Their manufacturing process is also certified by eco-INSTITUT, which means the mattress passed testing for quality and health of materials. Awara also teamed up with global climate advocacy group, ClimatePartner, who plants trees for every Awara mattress sold. Combine all that with the fact that Awara is designed to last a lifetime and has a forever warranty, and you don’t have to worry about your mattress sitting in a landfill for the next 100 years.
