It's a bit too soft -- chair makes indentations in the mat and then isn't able to move easily out of the "pits" it has formed so it's sort of "frozen" in place until I give it a big push.
The mat does not work as expected and I do not weight more than 190 lbs. The carpet was measured before I purchased and my chair sinks into the mat. Not happy.
Glad was delivered I would never have gotten into my car. I do have issues with it on hardwood floors it tends to slide around. Hopefully it will protect my floors.
