First the positive, it is a neat bed. The design is great.   Then the downside.  1) Some of the parts - the slats that go under each bed have not been properly sanded.  They are rough and you will acquire several splinters and most likely damage your mattress when you lay it down.  2) Not all the parts are cut to fit correctly, you will spend some time forcing pieces to fit.  3) And probably most frustrating, many of the pieces are not wood they are particle board and as such break easily.  A simple bump which would nick wood will cause a chip that you cannot put back.  Portions of the steps (the lip where feet go) are particle board glued onto wood and after 2 months of limited use cracked cannot be put back together.  As tempting as it is you are better off going with a Costco product (who wouldn't sell something this poorly made) or a real furniture maker who uses all wood and will stand by their product.
