When I purchased this product under the exact same Staples Item Number three years ago it was sold as "Staples Chairmat for Plush or Thick Carpets". Since I use it on a very low-pile berber carpet and only for home use I expected it to easily handle my usage. I weigh about 155 lbs and am using a 5-caster chair on it. I don't recall exactly when the cracks started to appear in the mat but I know it's been many months. Now the cracks are large enough that they prevent the chair from rolling smoothly until I pop the pieces back in place. For a chairmat in this price range and sold as a product for "plush or thick carpets" I expected it to perform better. It does have a "limited lifetime warranty" so I'll be calling the local retail store this week to see if I can get a free replacement.
Product does not stay in one place atop the carpet and keeps sliding around. Thought the bottom plastic protrusions with the weight of the chair would be enough to keep the flat chair pile carpet chair mat in one place. Maybe the protrusions need to be a little bit longer on the underside. I did not have the same problem with the previous product that I purchased at the same store. Hoping the plastic protrusions on the mat underside did not get smaller since I purchased the last product.
Bought this mat for my mother as I had bought her one of your office chairs but for her to use at her kitchen table. This mat works perfectly under her chair at the table. It's just the right size so it doesn't interfere with the rest of the regular kitchen chairs. Was easy to put down. Very happy with this purchase got $10 off.
This is a good very economical chair mat. It is a bit on the small size but otherwise works fine for my home office. Seems to be best suited for smaller spaces and less than heavy duty use which is what I need. I do roll off the mat when pushing back from the desk.
