The only concern we had is that it is a bit softer than the previous mat for my husband's desk chair. He did not roll as freely using this mat. We solved the problem by swapping it for my older rigid mat which holds him well. I am easily accommodated by the new mat but I weigh 105 vs his 195 lbs.
I was hoping this would work in my home office as I didn’t want to spend a lot due as this is a temporary work arrangement. The wheels of the chair actually dent the mat without even sitting in it. Then when you add your weight to the chair it is very difficult to roll. Might as well keep it on the carpet. I would not recommend this product.
