Organic mattress pads are available in organic cotton or wool. There's even a waterproof option. The primary purpose of all mattress pads is to guard against sweat and soiling. Place the pad directly on top of your mattress as a protective layer and cover it with your fitted sheet. What you’ll appreciate most about an organic mattress pad is it breathes and it's not chemically treated. Our certified organic cotton and natural wool mattress pads absorb and wick away moisture naturally, unlike conventional polyester pads. This helps keep you feeling dry and comfortable.
