It took me about four and a half hours to assemble this bed by myself. My fingers ached from tightening the screws with that little Allen wrench, but I felt a great sense of accomplishment, and I really love the final product. The storage space under the bed is incredibly practical, and the bed material is excellent. So far, there haven't been any problems. All the parts are sturdy, with no looseness or wobbling. This is a very stable bed.
