We didn't want a bulky bedframe because of our small sized master bedroom.  This was a perfect choice.  WE are not small people and it doesn't squeak, move around or slide in any way.  The support is great and cheaper than buying box springs.  Storage is wonderful under it, just slide boxes, etc. under from the sides of the bed.

Pros: price and functionality
Cons: simplicity if you want to count that as a con...really nothing!
