We have had this for six months and are well pleased with it. It has a lot of slats beneath the mattresses, making it nice and sturdy. The black finish can be touched up with a marker if it gets dinged. 

Cons: the ladder is uncomfortable on the feet for adults due to the slats being vertical instead of horizontal. The slats are rough and have dropped pieces in my eyes while changing sheets on the bottom bunk. 

Pros: this thing has survived crazy kids without any problems. It is inexpensive and sturdy.
