Took 7 of us to build it (maybe over-kill but still took us a couple of hours!). It's a very good size and looks good, however it probably does need to be actually fixed to the wall as it leans away once it's full. The 2 drawers at the bottom are also looking like they're falling apart a bit (a gap has formed between the bottom piece and the front); they haven't, but I've bodged them back together with a bit of superglue just to make sure.
It does the job and I am confident it will stay in one piece for as long as I need it to, but I don't think it would survive a house move!
