TEMPUR-Material™ is temperature sensitive, becoming very firm or freezing in cold temperatures and soft in high temperatures. It should be warmed to 65-75°F for optimal performance. If stored cold (below 50°F) and folded, avoid forcing it flat to prevent cracking. Warming it indoors will restore its proper feel.
TEMPUR-Material™ is temperature sensitive, which means it can become very firm, or even freeze, in cold temperatures and can feel very soft in high temperatures.
We recommend bringing the product into a warmer room to help bring it to a normal temperature range (prime temperature being between 65-75 degrees Fahrenheit) for it to perform at its best. If the mattress, or other Tempur-Pedic® product with TEMPUR-Material™, sits in cold weather (below 50°F) folded, do not try to force it to lay flat as the material could crack or split. It may take a few hours, depending on the temperature of the room and the size of your product, but the TEMPUR-Material™ should warm and soften to its true feel.
