Large Desk Stand Riser Using Basic Shelf

SummaryModified Jerooney's model to work with a standard 11-3/4" x 5/8" (299mm x 16mm) shelf board from the hardware store.Also added a peg leg in the center as I cut my board to 45" and I did not want to see any future sagging. The end pieces are rather large but they fit on a 300 x 300 bed flat laying corner to corner.
