Ive had this bed for my boys for over 3 years and it is still as sturdy and strong as the day I received it.  Excellent purchase and I shopped around very hard for the right bed.  The beds are super super spacious, you can literally fit 3 people comfortably in each bed and they would not be touching.  If your looking for a bunk bed, this is it!!  And the staircase has storage which is an added bonus
