I bought this for the top of my daughter's bunk bed.  It was quite thin and measured 5" thick instead of 6" thick, so I was disappointed and worried about how comfortable it would be when she slept on it.  Right now she's only using the bottom bunk, so it's not really an issue.  But I still worry about when someone uses the top bunk, what type of sleep they'll have.  The ordering process was great and it came squeezed together in a bag rolled up like a sausage!!!

Pros: Great value
Cons: not 6" thick
