Got this chair mat to go with the awesome chair we bought for my dad. Mat wasn't quite as thick as I hoped it would be so even though it does work well so far the chair wheels still make a bit of a divot in the mat making it a little less than ideal for my elderly father. It is however much better than he had before (cheapo chair that had fallen apart with no chair mat at all for the carpet). He's happy though especially with the chair (which is super comfy and easy to operate). If I had it to do over again I might buy a little thicker mat. However I went with price... (Yeah I know you get what ya pay for...)
