I like everything about the mat except for the thickness. It is thin so when I have to move my chair when I am sitting on it the bumps make it her to move. You can't glide.
This is my third. I have two others that are over 8 years old with nearly daily usage. Sure it's soft but the hard polycorbon one I got from a certain online seller started cracking after 2 years. These are the ones to get if you want a long lasting one.
