This took my 11 year old and me just under 3 hours to build. (I am also 6 months pregnant). The directions were easy to follow. This bed is VERY sturdy. We still need to purchase a third mattress, but only 2 kids will use this room. This was a great buy!!! We almost went with the wooden beds, however, the weight limit for this steel frame was actually much higher. The top and middle beds can hold ￼200 lbs.
