Very solid bunk bed. Took about 4 hours to fully assemble with 2 people. Probably would have gone faster but the instructions were confusing as they did not have the same p/n as the boxes.  Had to un-box almost everything before we got the hang of it.  I would recommend putting screws in all of the lats. We only put screws in the ends but one came loose and fell down. Despite the negatives mentioned above I would still highly recommend this bed.
