My husband measured the room them cut the pieces to fit. He sanded down the edges of each to give it kind of a rounded look. You can buy the sheets of metal at Home Depot and trace a pattern on it with a sharpie. I cut them out with metal cutters, sanded the edges and then at each corner where the wood meets, I screwed in the metal squares. I spray painted them first, a darker brown. Here's a closer pic which may give you a better idea of what I did. What helps hold them down is the carpet and pad underneath the wood.
