Converting a Full sized Storage bed into a Queen

I made a mistake and purchased a Full sized storage bed frame, however I was able to easily modify it to fit my Queen mattress and the solution works perfectly and solves problems I have seen with all other storage beds!
My measurements were 54" x 74" and I had to cut 2 sheets of 4x8 styrofoam insulation to fit these dimensions. I cut it with a box cutter but then had to move to a knife after making the intiial cut with the box cutter, because the box cutter blade wasn't 2" long. Taped the edges with 2" white gaffers tape to prevent styrofoam from shedding afterwards.
