Our kids have been sleeping on this for a few nights and love it.  The beds seem very sturdy, the stairs a little less so, but still good quality.  It is very large once assembled so be sure to measure your space in advance.  It is nearly impossible to move once assembled so be sure you build it where you want it to stay.  My husband is handy and did this himself over the course of 4-5 hours.  I love that this becomes two spearate beds once they outgrow wanting to be in bunk beds.
