Received but is Not what I needed. I needed a much thicker mat to take the weight of both my weight & the Chair. The one I received curls up causing me to trip and fall and leave dents of the wheels. The type I need is as thick as the same in heavy vinyl or glass types. Please let me know the proper type. I still was able to find an area to used this one
Used at home office which is adequate. Would not be sturdy enough for daily use of 4 or more hours in an office situation. Pleased due to the low price that I paid.
