Quality of wood is fine.  The bunks are very sturdy once assembled.  The bunk beds were very easy to assemble.  Most of it can be done with 1 person.  Needed a helper twice in the process.  The trundle should have had pre-marked holes and we had to really make sure we were screwing things in the right place but otherwise was fine.  The price was good & we got the delivery in a timely manner.
