Which means you don't have to worry about nasty chemicals or metals being present in your mattress. This top open-cell layer is made of 2 inches of latex to help you sleep cooler (Even during summer nights). This is a second layer made of 1 inch of memory foam for supreme comfort. Fun fact: Memory foam was invented by NASA-funded researchers looking for ways to keep test pilots cushioned during flights. High Resiliency(HR) foam is designed to help your body feel like it's resting more naturally.
Mattress should be protected against any liquid spillage at all costs. This is not just for Sunday mattresses, but applicable to all mattresses. Please do not expose the mattress to direct sunlight. We are referring to leaving the mattress in the open, exposed to the sun. Sunlight that comes into the bedroom through the windows is fine, but not direct exposure to the sun in the open.
