At least once per week I have to move my chair and pull the pad out from the desk because it creeps. It is a little "soft" and the chair casters tend to sink in some and you need a little effort to overcome the "holes".
Got it cause others were almost double the money. It should have. After 1 week you can feel isn't thick enough and will break in a matter of months. Use it in my home office every day usually change chair matt every 8-10 months this one will last way less.
Although this started as a pliable adequate covering for a rough wood floor in front of my desk it began hardening and cracking within a few years. As long as you know that a rough wood surface won't stop it from sliding around and that it probably won't last too long it will do the job for a while.
