After searching for a high quality/durable chair mat the Staples Cust Svc Rep recommended this item because it was thicker and less expensive than comparable mats on the website for thick carpet. I ordered it installed it and returned it within 4 days. Mat is not strong enough to support my weight (157 lbs) without creating a depression and aggravation moving the Staple's brand desk chair around on it. Specs look impressive however this is not effective for thick carpet.
I am certainly satisfied with the floor mat but the label glued on not so much. It took several different kinds of products to remove it without damaging the plastic.
Mat does not stay secure on carpeted floor. I am constantly having to move and re-adjust it. It seems the backing spikes are not pointed or long enough to hold it securely in place. It is also very soft and casters cause indentations. For what it cost I expected much more.I'm Not a happy customer.
