bamboo chair mat:

Now you don't have to put up with a utilitarian plastic pad to protect your flooring
form being damaged by a rolling chair. This handsome bamboo mat rolls out, making
it easier to handle than stiff plastic mats. In place of "spiky" backing, there's
a high-density felt that cushions as it grips.

It has warm, honey oak finish with scuff-resistant polyurethane coating. It is made
of 100% Anji mountain bamboo, one of the strongest and most durable bamboos available.
