My plastic chair mat was cracked and broken in several places and after a while, even duct tape didn't work. My husband had a great idea about using quarter inch plywood instead. He bought a 4 x 4 ft. piece for a lot less than the price of a new plastic mat, and this will last a lot longer. It's also smooth enough that I still don't have to wear shoes in the house. Why pay $50 plus when you can spend under $15 for plywood. You can stain or paint it if you like, but we haven't.
