i read the review before purchasing the item, so i was not surprised when i saw the gap between the mattress and the bed. it means the size is not exactly king, but it's not that bad, especially for the price we bought it.   
the only issue was with the delivery guy. he was asking me to come down and take it by myself! because he couldn't find the right entrance to my building with a truck. it was super heavy, i don't know what he was thinking but i didn't came down, so he came the way i told him, and then he was "crying" me about how much the paid him for this delivery and  he was so upset that i'm living in a building that he have to walk a lot .... what do i even care? and what can i do about it? he gave me such an unpleasant feeling ....  

Pros: great price, fast delivery 
Cons: Measurements not accurate
