Bought this for me and my roommate in downtown San Francisco. We are both 22 years old and the bed holds up great. The instructions do require a fair bit of work (drilling, alignment, etc) and it took us about 4.5-5 hours to build it. But what a great buy! We both have tons of space. The top bunk can even fit two people on it -- but to be safe, we generally don't put a person on the bottom bunk when we do that.

Only 4 stars because some of the wood is chipped and looks prone to breaking sometimes, but we haven't had any problems so far and it has been 6 months.
