This chairmat is the perfect size for our needs. The carpet is practically flat and the grippers on this mat hold just the right amount. It makes it easy for our secretary to move between work areas without having to get out of her chair. The mat lays flat is not curling like the old one so it does not create a tripping hazard. I don't know if it will turn yellow and crack like to old one did but right now it is clear and very pliable. I don't think it will harm the carpet underneath and it definitely protects the carpet from the rollers on the chair. I would highly recommend this product.
It is made for hard floors but I find it does not stay put. In order for this to stay put on the hardwood you need to have some kind of backing or anti-slip material to keep the product from moving about. So if you are looking to have a mat that doesn't move this is not the product for hard wood floors. What I ended up doing is buying the matting that is used for area rugs and cut it to fit the mat. Now it does not slide. By doing this the Hard Floor Mat protects the floor and I get to keep gliding about the floor with my chair.
Am very happy to have gotten and am using the hard floor chair mat for my computer desk. My chair rolls around so much better than it previously had. Found the product on a sale and free shipping. That made it a whole lot more attractive. Am very glad I have it now.
Not as described. Lip is over 25 inches wide and therefore won't fit under my desk. Also tracking system says it was delivered on 05/30/2014. This isn't accurate. It was delivered on June 1 2014. Ordered it on 5/26 and expected that it would be delivered on 5/28. Not sure why there was such a delay but when finally delivered it was filthy dirty and looks like it may have been previously used. Not what I expect from Staples!
