Sleep Number's New Adjustable Mattress Ships in a Tiny Box

But if you live in a tiny apartment, with a tiny staircase leading to your front door, it makes wrangling a big fancy mattress a nightmare. So Sleep Number designed a new adjustable mattress called the 'it bed' that arrives in an easily maneuvered cardboard box.
