I only gave it 2 stars as the wheels from my desk chair leave dents. It's not too much of a problem as my desk is in my bedroom but it is unsightly. Other than that the chair moves easily.
If you have hardwood floors without carpeting and you use an office type chair with casters this is perfect solution to prevent wear and damage. We have solid oak flooring and noticed the casters where starting to mar the wood surface. Purchased this mat online had it delivered to our local Staples. It worked out perfectly! Price was right decent quality. Just make sure you thoroughly clean both sides of the mat and your floor before laying the mat down. This is the third mat we've purchased from Staples and we're totally satisfied.
Bad all the way around. Delivery came after 9 p.m. mat was not enclosed in a wrapper and there were footprints all over the face of the mat. Then I noticed a 'warning' pasted on the mat that it contained possible cancer causing materials. I certainly didn't want to take chances with my animals. I returned the mat to the local store and purchased a suitable one from another store!
