This mat still slides around on the carpet ... the nubs on it are much too short to dig into the carpet and keep it in place. I would not recommend it.
I might have been spoiled with a really high quality chair mat before but this is a bit flimsy. It is protecting the carpet okay. I use it to put underneath my standing desk. My footprints and the wheels of the desk are making strong indents into the pad but the carpet is okay. Reasonable quality for the price.
I used this under a rolling chair in my hobby room. It is smaller scale than some I've looked at and so it fit nicely. It grips the carpet well and stays in place. I had a coupon for 25% off so it was a good bargain for me and my use
I bought this to replace one that had cracked. It was three years old. This one does not seem as sturdy. Feels so much thinner and is much lighter. I'll see how it holds up.
Felt pretty heavy duty in the store. My carpet is only 1/2" thick but mat dimpled where chair sits almost immediately making it very hard to move the chair. Was supposed to be good for carpets up to 1". I only weigh 170 lbs and my chair has 5 rollers. Very disappointed.
