It works but is very thin compatible to one it replaced the rollers on the desk chair sink thru it easily - so I will need to replace it with one that is of better quality
This mat works pretty well. It allows my chair to move more smoothly over the carpet. However the plastic is soft enough that it will temporarily deform and create little "ruts" - and I'm not a big person (165 lbs.). These requiring a bit of a shove to slide out of.
