Bought two of these, very stylish and once put together solid BUT an absolute nightmare to put up hence the rating, the second one I did took 5 hours!!,  I'm an experienced DIY'er and even knowing what to do after the first one. 
4 or 5 tubes of wood glue, loads of screwing and 1 of 4 of the supports for the drawers wasn't pre- drilled to accommodate the 4 wood plugs, so had to do it myself.
