My last mat had started cracked under the weight of my new chair, which weight around 50-75 lbs.

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!!

After it became obvious that the tiny wheels on my rolling chair were slowly destroying the cheap linoleum floor at my desk, I decided to purchase a protective mat.
