Excellent quality product. Fairly easy to move across the floor on a lightly used floor carpet. The only drawback it does not have handles molded into the mat shape for easier mobility.
As far as I'm concerned I would've been better off putting my chair straight onto the carpet. I have very shallow carpeting with almost no padding underneath and yet my chair STILL puts ruts in the mat and the carpet underneath. Worth noting that my chair has SIX rolling feet so my weight (160lbs) is definitely well distributed. It's nearly impossible to move the chair a little bit and have it stay in place without having it uncomfortably pull back towards the ruts. Also the gripping spikes are pathetic little nubs that do NOTHING the mat itself moves forward slightly every time I sit down and push my chair forward. Once the mat moves forward enough that the chair falls off it (Which takes only about 3 times of standing up and sitting back down) it's impossible to get the chair back on the mat without pushing the chair back and lifting it to get it back over the lip. I constantly find myself pulling the mat back where it's supposed to be. Plus the darn sticker they put on it was a pain to take off and took a few minutes of scraping to get all the residue off. Don't waste your money on any of Staples' garbage mats when you can spend half the price for a much higher quality mat at another office supply store. Long story short this mat went straight into the garbage.
