I needed to off-gas the floor mat and weight it down to straighten it from it’s rolled form but it’s worth it. I can move my office chair easily and effortlessly now.
I bought this quick to set up my home office with the work at home mandates. It's so thin that there are now dents from my chair wheels so my chair doesn't move easily. It would be ok for hardwood but not any carpet. I think it will eventually crack where my wheels sit most of the time and need replaced with a heavier one.
