another accident we had with an a wardrobe two of my lads had which was a funny one in retrospect but  i some when you carry a wardrobe,funnily enough, the easiest way often if you've got a tight corner, you know as you go round a corner in a staircase you'll come from a landing and often turn right or turn left to go down, if you put it at an angle like that then you won't get it round the corner without catching the bannister.
