we have a full. 3 fit fine for us, we can (and regularly do) do 4, its definitely "snug".
id love something bigger, or at least a twin on the side or something, but mattress chemicals scare the poop out of me. (hence why we only have a full, it was get a full size that wasnt scary, or larger that was.) and i havnt been able to justify the cost of adding more mattress to our room with my standards.
that said, i also have a pp's issue, of stuff not fitting up the stairs. weve had to do the mattress on the floor because the foundation (boxspring) wont go up the stairs.

. I'm thinking of getting a crib mattress to put up next to the other side of the king once the new baby comes. I guess my goal is to have the entire floor be covered with beds 


). We fit, but I'm glad we have the extra space of a queen+full at home. I'm also very, very glad our apt has large enough bedrooms for the mattresses to fit comfortably!
