We bought this in a King size for the 'spare' bedroom to accommodate our two recently married older kids and their spouses.  (To replace double beds!)  First of all, this was going into our basement, so the fact that it comes rolled up in a box was one thing that tipped us toward this purchase.  This bed is NICE!  So much so that we are considering ordering another one for us to replace our 10+ year old select comfort.
