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.
The stick on tags that came on these were super glued on! Took me a lot of time to soak in 409 and scape them off! These things are very thin and cheap. Half of my staff wont use them and I bought them better ones locally. The wheels on the chairs sink into the plastic making it hard to move about.
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!
Smaller size is preferable for a home office. The other two models available at Staples may be great for a commercial business office but the smaller one is perfect for my smaller home office.
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.
