At my office my desk chair was located near my desk but had to be pushed backward forcibly due to overlapping carpets. I was manually lifting the chair. So we went to Staples to shop for a plastic mat. A very helpful sales person found us the perfect size and solution. Now my chair moves smoothly. I recommend the use of this product. Thank you Staples!
The vinyl chair mat does the job but even after short term use you can see depressions forming. It will not last beyond a few years but if that is good enough for most people then it is fine. It does work well in allowing my chair to move over a carpeted floor.
The mat is satisfactory. However the thickness is insufficient to prevent chair wheel depressions in the mat after sitting too long before moving the chair.
This Staples Model #: STP-17436 which was in stock at my local store and was supposed to work with an 1/8" flat pile rug but was too thin and chair would not roll. Returned and purchased model 20229-CC designed for a 3/8" flat pile rug which works just fine. I have three of these.
