my old chair mat never caused static electricity. This mat is made of a different material that must conduct static. Sometimes I get a bit of a bite when I touch things after rolling across the mat. I do also have a new chair so it could be the combo of both causing the static. You can't beat the price of this though.
I'm 6'2" 220lbs and already there are massive dimples in the mat...almost like dents will keep an eye them to see if there is any cracking or perferation in those areas...and keep my eye on the warranty and glad I used my AMeX card because it doubles the warranty...probably only 30days... I guess you get what you pay for
I bought this chair pad to stop my office chair from destroying my carpet. It is so thin that my chair continues to indent the carpet. Even worse the chair rollers get stuck in the indentations and I can’t move my chair without getting up first. It should clearly state it is not for carpet.
