Assembly the time taken (30-45 mins) i feel is not relevant to the items rating, but worth knowing at the most.
Quality excellent build, 3mm gaps between drawers which doesnt show in images (advertised image shows no gaps at all).  However its sturdy, looks like higher quality than you might expect of flat-packed furniture, I recommend this unit, you wont be dissapointed for its cost.
Note some comments refer to frustration regarding not knowing you must attach this to the wall you can if you want to, the attachments to do so are included but it stands well without any support as does any set of drawers.
