Very sturdy and looks good.  I'm a teacher with lots of heavy lever-arch files and I now have somewhere secure to put them (with my other stuff).  Because there are lots of uprights, the files and books are less likely to slide over.  It was reasonably easy to put together, though I did have to ask my friend (whose hobby is weight lifting) to help me get it upright once I had assembled it (we are both women).  It smelt a little chemically for a month or so.
