This Deep Dream Mattress was sold online to us by Lifely.com before the company changed name from E-Living Furniture. The mattress was supposed to have the latest in cooling materials inside to keep those is a warm climate cool, and a cool refreshing sleep. For 2 years this mattress has been nothing but drama. Lucky for us it comes with a 20 yr "manufacture warranty" As anyone can see, the manufacturer did not use any of the cooling materials as guaranteed by advertising and sellers. If you live in a warm country like Australia, keeping cool is a priority. This mattress does the exact opposite.
