Natura’s organic line of mattresses is made with certified organic materials, which means they are chemical and pesticide free. All queen-size mattresses in this line are made with 8 lbs of 100 per cent certified organic wool.For centuries wool has been dubbed “the miracle fibre” and science has never been able to duplicate it. The crimped structure of NaturaWool fibres creates millions of air pockets that ensure an insulating layer of dry, comfortable air next to the skin. This layer buffers the body from extreme cold or hot air, maintaining a comfortable temperature at all times. This relieves the body of thermal stress and steadies the heart rate, allowing for longer periods of deep sleep.
