What a waste. I ordered this to allow my desk chair to move easier around my office space. What I got was a patch of plastic that is worse for chair rollers than the carpet. Way too soft for using a chair. They should market this as a large clear yoga mat maybe then it'd be accurate.
Not very thick - so after a few hours of sitting the wheels of the chair create indentations in the mat thus making it more difficult to roll the chair - i'm average weight of 160 pounds too...
Any time you have a chair that rolls on carpet numerous times you need this type of mat. Not only does it make the chair easier to move but it save your carpet from excessive wear.
