Question: can you use a full size mattress on a queen size frame?
Answer: For the bed with a wooden headboard and foot board and two metal mattress support bars, check to see if the support bars are adjustable and can adjust from 80 inches for a queen-size bed to the 75 inches for a full-size bed. ... Evenly space the marks for the bolts from the centers of both the headboard and the footboard.
