I bought this to use under a desk. The chair that sits on top of it is very light and has hard plastic casters. It is being used by my child that weighs under 100lbs.The product has dents in the material from the chair. It is very hard to roll on top of it! I am not real pleased with this product.
This Chair Mat is too soft. I even purchased extra large chair casters to more evenly spread the weight. It did help. There are depressions on the mat and I can't slide along it.
I have worked in offices for a very long time and know the difference of quality. This is a good buy.I wasn't sure it would be as the thickness is hard to guess but it works very well.
I bought this mat as a replacement and it works excellently. The previous mat lasted me 5 years but was cracking in the center because it was a folding chair mat-- the center seam finally was breaking away. This mat was a great value for the money and I highly recommend it.
