Durafoam and memory foam mattresses contain polyurethane foam which provides a firm level of support while allowing air to circulate through the mattress, decreasing heat buildup. Polyurethane temporarily maintains the shape of any object placed on top of it that exerts pressure.
If needed, you can use water on your Durafoam mattress to remove dirt or stains without harming the foam, according to the manufacturer. Memory foam mattresses will disintegrate if placed in a traditional washer, so spot-clean stains when needed.
Several manufacturers produce memory foam mattresses, and the warranty period varies among manufacturers. The manufacturer of Durafoam mattresses offers consumers a 25-year warranty.
Any product containing polyurethane foam has the potential to catch fire, according to the Polyurethane Foam Association. However, manufacturers may choose to treat foam mattresses with flame-retardant chemical applications. Durafoam's manufacturer claims that Durafoam mattresses have flame-retardant characteristics.
