This bed was easy to assemble and slightly higher quality than what you would find at a discount store. The steel used for the frame is very thin and the structure isn't designed well. We use it for two small children which is the only amount of weight it can hold safely and even that is debatable. I'm afraid if someone sits on it with enough force, it will bend and render the bed useless. Worst of all, the casters that came with the lower bed are the worst quality casters I have ever encountered. On the first day in use, bearings were spilling out of them and within a week, we had to remove all of them and resorted to dragging the bed across the carpet. I thought about asking for replacement casters, but I don't want to be sent the same poor-quality ones. I'll be going out and buying some replacements. This was a big disappointment. I'll likely be listing this thing for sale at a deep discount or giving it away. Stay away from this one.
