Works great! Had it for two months. Recommended over glass or standard vinyl - I've used both.
After my glass chair mat shattered into a thousand little pieces after 10 months of use (rated for 1000 lbs., it said), I had to go back to plastic. Couldn't go through that again. But I switched to glass for a reason! The vinyl mats - even the thickest ones (which I have bought in the past) - still deform under the chair wheels, making it hard to roll. Then after a number of years the vinyl wears out and cracks where the wheels roll on it. Lovely. Trying to find another solution I came across this one. Perfect! I've used it a couple of months now on my medium pile rug. This mat is wonderfully rigid and doesn't deform, just like the glass mat, at like 1/3 the weight of the glass mat. Recommended!

Smooth sailing for my office chair that has locking wheels when they are required.

This has been an excellent chair mat for me, since I am in this chair working on computer and technology issues most of each day. So far, I have noticed no wear. It seems quite solid, and is easy for the chair to roll around upon.

I've been looking for a high quality chair mat that will stand the test of time for years and I believe I've finally found one. Loving it!!!!

We purchased this for my 91 yr old dad, who uses a walker and trips easily, this solid mat does not indent, stays rigid and is much safer than his previous mat, dad's very happy!! Great Job A++++++
