The mat is too soft. Indentations from the chair were immediate making it difficult to move the chair. Do not recommend. Expected a higher quality of product.
Useful only on hard surface-like carpeting such is indoor-outdoor. The mat sinks under the chair rollers on any carpeting with higher pile thus unable to move the chair without lift up out of the chair.
We bought these mats to go in a home we just moved into which had a rug with high pile in the office area. These mats are great at allowing our office chairs on rollers to glide easily.
