I bought a sheet of plywood and told the man the size I needed out of it and he cut it to the right size for free. I took all the plywood home with me. I bought a long dresser at a second hand store and decided to put the plywood on top of it. I covered the top of the plywood with batting and then a piece of fabric and stapled it on the underside. I put it on my dresser and it stays put when I iron. I didn't have to add any wood to keep it from moving around because it doesn't at all.
I love using the dresser because I filled all the drawers with fabric and other quilting items I use. I still have my ironing board in my garage in case I need to iron sleeves or something like that. But I did it all myself. The staples were a life saver to me.
