I bought two of these for my boys (8 and 11 yrs). They had an old bunkbed but had it laid out as two beds in their room. Since no one wanted to sleep in the bottom bunk, the whole room was bed. Now their desks and dressers are underneath the beds and the whole room has alot more space opened up in it. They were easy to put together and they are sturdy, My 11 yr old weighs 162 lbs and he does not feel unsafe crawling up into it. We did have to buy an extra tool to put one of them together because the weld had left a burr in one of the screw holes (about 25$) and one of the boxes was missing the manual but this was not a problem for us because we had bought two. There is plenty of clearance on top as we have ten foot ceilings. I would recommend this to anyone for upgrading the kiddie bed to a preteen bed. 

Pros: nice price, fast delivery
Cons: might need additional tools to finish, might have to download instructions from internet.
