I used two small bookcases that were 24" wide and 32" tall as the supports. Then, I added a purchased piece of melamine board that measures 30" x 48". I bought the melamine adhesive stripping to cover the raw edges around the board. This is working very well for me and was only a minimal cost. Gives me storage space below, too.
