I bought this for my kids in full over full, after a metal set was just too creaky to tolerate any more.  I was very impressed with how sturdy this set is.  I love that the slats are drilled in place, not just set on top.  I also love that the weight limit on this will hold them until they're ready to purchase a bed of their own.  They were very quiet and not at all wobbly when stacked, and now as separate beds they're a very nice, neutral style.  My 6 year old loves the rail on the top bunk.  It makes her feel more secure.  The grey is also a very soft neutral that works for a girl or a boy.  We've moved with these once with zero issues.
