My kids want to share a room, but the rooms in this house are small so when the eldest needed a bigger bed, I decided to go up. For standard height ceilings, this bed is pretty tall. I wish I'd have taken the main legs to someone and had 6 - 9" taken off before I assembled it. Also, the hardware is cheap and soft, so the bolt heads strip out very easily.   That said, it is holding up to my 14 year old just fine so far. 

Pros: Great way to save space! Looks appeal to young boys. Easy to put together. 
Cons: A bit too tall for typical houses, cheap hardware makes for a wiggly bed.
