Love this unit!  My hubby was able to put this up by himself fairly easily - and he's not the best diy guy! 
The reason we went for this one was for the adjustable feet as we live in a flat with old sloping floors.  The feet are only just long enough fully extended. It would feel more secure if the metal on the feet was a little longer...but then our floors are unusually wonky! The only thing that could be improved on this piece of furniture would be if the holes for the screws went all the way through.  For some reason they aren't and it breaks the wood off at the back but then you can't see it as it's against the wall so, doesn't really matter!
