The mat is so thin and soft as opposed to firm and solid it was a waste of money. My chair sinks into it and then becomes difficult to roll. I will try to return it.
This is very soft and floppy. My chair sinks and makes it very hard to move. Every day at least twice I have to scoot my chair back and reposition the mat it moves around a lot. I have over the years had multiple mats from Staples for the two desks but this by far is the worst. I am using it on low pile carpet. I guess it would be ok on tile or linoleum.
The mat is too soft for carpets even though it's supposed to be for high pile carpets. Even empty a chair will form divots in the soft plastic that are difficult to roll out of.
