I had one of these mats before and it gave me several years of good service. When it was time to replace it I looked up the product number and reordered. To my surprise the plastic is now much softer. Instead of rolling over it smoothly as I did before I find my chair wheels create ruts in the softer plastic and I have to lift the desk chair in order to move it. I will not buy this again
I ordered this online twice and should have sent it back again but didn’t want to deal with it. Both times in receiving the floor mat it was very dirty and scratched. When you pay $76 for a floor mat you should expect to receive it in good shape not like it was taken off the floor used and sent for my use. I’ve used Staples for years and this isn’t like them to send something in poor shape.
I guess my carpet is Med pile b/c this mat gets dented by my office chair wheels and it keeps on moving towards the right and 'bumping' into my desk and denting. I literally have to move it back twice a day. It might be perfect for a low pile carpet but I wanted to write this so if you're not sure if yours is low it probably isn't and you'll be disappointed with this mat.
