I bought two, one for each of the sides of a bay window.  I measured carefully as one was to fit round an electric socket - But made a mistake and they were just a little too high.  However on it's side it fit perfectly and I love the asymetrical look.  Fortunately I tried it before making up the second one so I didn't put the feet on it.  Also on it's side  ringbidnders can be stored upright on the shelf.  It took over an hour for the first one and about 20 minutes to build the second one.  Some of the holes for the rawl plugs were very tight but using a coaster to protect my fingers/hand they went in with some effort.  I'm a not very strong pensioner lady.
