I have just had new beige carpet installed in my home office. The pile is
much deeper than the carpet that was replaced, so much so that my chair
does not roll on it.

I know I can buy a plastic chair mat but I think they look tacky. So I now
have a sheet of 9mm MDF on the floor. Now the chair rolls perhaps a little
too easily, but hey the color is just about the same as the carpet.

Since the MDF is just about as tacky as the plastic would be, I got to
thinking that perhaps there is a good wood solution to this problem.

Has anyone built such a chair mat? Do you have any suggestions for something
that looks good, is durable and has rolling resistance a bit greater than
the MDF surface?

Built a floor mat, 4' x 8' 1/4" Oak plywood with some trim and bracing
under. If I were to do it again 1/2" plywood.
