I installed this bed last week, it took me 2 hours Saturday & one hour on Sunday .I am going to work on the second part (the trundle), hopefully tonight. I a had problem with the some of the nails , which were difficult to insert. There is still one nail that despite my effort, could not be inserted.  I will most likely have to go to home depot or Rona to buy one. overall I am happy with it, I just wish a little more stable.
