My boys just love this bunk bed!  It is sturdy and they have so much fun.  My boys just turned 5 and 2 12, the stairs make it very easy for them.  We went with 9inch mattresses and it’s perfect, u could also do 8 and it would be fine.  It is a nice looking bed for sure, looks very sturdy.  Looks nicer than it does in the pictures online even.  It does have a few wood blemishes but nothing that would stop me from buying it.  No one can see but me since I spent the money, I looked with a fine tooth comb.  Def a perfect bunk bed if you want full over full with stairs vs. a ladder.  We also went this the storage drawers.  They aren’t on any rollers but they are still very easy to open on the carpet.
