Nice and inexpensive mat. I need a chair mat for my carpet now that we are working from home. The spikes under this one are not sharp but still grips the carpet firmly. Might not work for the short/berber carpet.
IT DOES THE "TRICK". After trying ROLL-OUT floor covering that only gathered up causing wheels of my chair to get jammed thought would try this and NOT at all disappointed.. but think could have used a larger mat.... probably next time...
