I bought this after reading many of the reviews, including those who were not as happy with the product.  I have to say this met my expectations and I am very happy with it.  I bought this for my Grandsons, 10 & 4.  The room isn't large, so I didn't want something real bulky.  This fits the room perfectly.  It is sturdy and the boys like it.  I like that the ladder doesn't sit on the floor and move.  This way no one gets hurt.  The side rails on the top bunk are tall enough for safety.  For the amount of money you pay, I don't think you can get any better than this.  Also, didn't need one of those bunky boards, the rails work just fine with the mattresses we got.   

Pros: Great value, doesn't take a lot of space, safety features like tall rails and attached ladder.  
Cons: None
