I use this mat in computer room which has a hard wood floor. This mat is perfect for the space that I have and works excellent on hard wood floors. It doesn't slide and has a nice smooth rolling surface. I would recommend this if you need to cover a small area and do not need to move your chair around a lot. If you have a bigger area I would recommend a bigger size.
in the write up no mention was made that the chairmat did not have spikes on the bottem to stop sliding...the model in the store has them plus hand holds on the side to help moving....i was very disappionted in the chairmat from the internet.....i am using it but not happy.....
