We just had new carpet tiles installed and got a bunch of these chair mats to replace our old ones. They are smooth to roll on and do the job to protect our new carpet investment.
After our move I missed the old mat and could see that carpet needed protecting. Mat was same as prior purchases and will do it's job. Need a way to cut off tabs for hanging in store. I had shears so no problem but needs to be addressed
I ended up buying two chair mats as they are too thin and the wheels on the chair sink into the mats preventing easy rolling. I weigh about 175lbs so didn't think this would be a problem. Using two mats helps but turned out to be a more costly fix than I had imagined.
