I was very impressed with the high quality of these beds upon purchase.  The have a very attractive appearance and look like they'll last for a long time.  My 4 and 6 year old boys love them so far, and they fit comfortably in a room with 8 ft. ceilings.  Space between the beds is adequate for a young child, but would be minimal for a teenager or young adult.  We'll most likely be separating the beds before then.  The assembly instructions were not very intuitive and pieces were not all labeled - so assembly took a bit longer than it might have otherwise - but all, in all nothing too complicated.

Pros: Quality, Durability, Appearance
Cons: Assembly Instructions
