Needed a bed for College kids. Top bunk is rated to hold 400 lbs, bottom one even more. Solid piece. I am very pleased. It was kind of a pain to put together, but well worth the patience invested in turning the screws through the pre-drilled holes. We put it together by hand. If/when we ever move, I will use a power drill/screw driver. Would have speed ed the process up if I had had one.
