We have seen a few different takes on a murphy bed, but have never seen one that retracts into the ceiling. The BedUp does just that.
With the bed retracted, you have home office space, or TV viewing space with illumination provided by recessed lighting in the bottom of the bed. Come night time, a simple pull of the handle brings the bed down just enough to clear the desk or couch that sits there during the day. No need to move the furniture before your sleep or vice versa, fix your bed when the morning comes.
