The quality is rather good. The bed is very, very stable and doesn't make much noise when you climb in. The metal is solid. Some design qualities I liked were the wide square ladder, the height of the bed (is the perfect size between a junior loft and a very high loft) and the fact that you don't have to climb over the side rail from the ladder when entering the bed.
My son loves his bed. We even made a little play area under that includes curtains. (For safety, don't use rope or string!)
It does take a few hours to set up and you do need minimum two people for this job.
