It is great size.  I got the queen size and it is very comfortable.  Took me about 3.5 hours to put it together.  I would highly recommend watching the video.  I was shorted some plugs but I got them within three days.  It is a wall hugger and I recommend placing it 4-5 inches away from the wall.  Use wood glue on where you see wood plug goes into hole just to make it a tighter install
