Very sturdy and attractive bunk beds. We are very happy with them and the kids are totally geeked about them. They were a bear to assemble, though. There were several details that were not adequately illustrated in the instructions. For example, the placement of the ladder holes and which side is the top versus the bottom of the bar the ladder attaches to. Also, assembly is definitely much easier as a two person job. 

Also, under bed storage is great with these. I've stashed several large storage containers under the bed and they easily slide right under. I was worried that the center bar would prevent that, but the center bars are just on the edge of the bed, not in the middle, so containers easily slide under the entire length of the bottom bed.
