They are trying to make you believe that it is something new and special. Mattress in the box has been around for about 10 years. Simply it is a foam or spring mattress that is put into a plastic bag and all the air is evacuated to cause it to compress into about 1/4 its size before it is rolled up to save transportation cost. You can buy one and bring it home in the trunk of you car. These mattresses are available at many furniture dealers and at Ikea.
