Seems very sturdy.  It is laminated pressed boards but it looks very nice once it is together.  Some of the instructions seemed out of order.  In other words, I think some steps would have made other later steps easier.  Like when putting the legs on the bed... put the center support legs on BEFORE you connect the two shelf pieces... We about blew the pre-drilled holes out of the bed because that was listed as a later step in the instructions.  It took us 7 hours to put it together.  Overall, we are satisfied at this time.  Our 10 y.o. loves it & our 12 y.o. is a bit jealous!
