The sofa comes in two packages and you have to put it together with the parts supplied.  You will need a helper and patience, it took me an hour and a half working by myself.  The contradiction is that although not that comfortable to sit on, it is really comfortable as a bed.  I guess the innerspring cushion supports you body well for sleeping, but is a little too stiff when sitting on it.  As a bed this is far better than the traditional pull out sofa.  The measurements are 72 length between the arms and 40 wide in bed position.
