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 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.
I received the mat and was very very disappointed. I was not like my old one. My old one was thicker and more sturdy. Yours was very flimsy and very hard for the chair to roll on. I am very displeased to say the least.
