This mat is not able to keep the chair from forming indents that makes the chair hard to move. I am a small person so weight is not the issue. Would not buy again
Spent the extra money because the first one slid all over the floor. This one isn’t any more stable and the teeth to hold it in place on the underside aren’t any deeper than first one.
Even the weight of just my chair puts dents in this mat. So when I sit in the chair it feels like I'm driving in a road with a lot of potholes and ruts.
