This bed is so sturdy!  The stepsdrawers are amazingly deep and smooth sliding.  We have had a 6’2” man in top bunk with our 4 year old and not a wiggle or noise.  It is so heavy duty that we could actually sleep our entire family at once and probably the only sound you would hear is snoring.  My 26 year old daughter spent a day and half putting 90 of it together with about an additional 10 help from others in the house.  It looks a little overwhelming in the 6 huge boxes, but just eat that elephant one bite at a time!  It is so worth it in the end!
