• Made with Natural rubber with puddle pad wool outer for moisture protection and bacterial control

Natural rubber is firmer than other natural type mattresses. A portacrib mattress generally is composed of a foam core with vinyl covering. Studies have shown that mice on this mattress have a reduction of 26% of their airflow. This could be a major factor in SIDS. Many studies have confirmed the link between SIDS and chemicals. These mattresses replace that foam with natural rubber and the outer with wool outer fabric for natural flame- retardance, water- resistance, bacterial resistance and dust mite control.

Because of the puddle pad wool outer: No need for separate puddle pad, it's already there. Easy to care for. Clean with gentle soap and water if soiled with anything other than urine. Otherwise just air dry and bacteria will die within an hour.
