I use this mat to go under my computer chair so the rolling back & forth on the carpet will ruin the carpet. This is the third one I have brought in the last 3 years and they just do not last the start cracking in the center and the hole gets bigger and bigger and pieces start falling off the mat. Should be more pliable.
Chair rollers dig in to the mat making holes and making rolling/moving around difficult. The chair gets stuck in the holes. You can see the seat roller holes although the holes seem to fill back in later after usage. This does not help while using and moving the chair around though. Suggest making the mat sturdier using stronger material.
I have had many chair mats through out the years. This one is finally everything I expect and more. The size is perfect and the thickness and crack resistance is the best. I would recommend this chair mat to all my business colleagues.
As I added under "cons" If chair has small wheels mat will crack over time. This is the 3rd mat I've purchased due to this. Larger wider wheels would negate the situation so the problem is not necessarily with the mat!
