Very happy with this product. Since we use it on a "no wax" tile floor it does tend to move somewhat as the chair is rolled on it but it doesn't slide completely across the floor. Staples is the only store we could find a solid non-cleated mat in this size. Since this was a special-order mat it came folded in a box and it took a few days with weight on the edges to make it lay flat.
Cheap but won't last long. Too thin. Chair rollers make indentations making it difficult to move around on mat. Sitting on carpet with padded underside.
