This is a useless product! It is worse than being on a carpet alone. The chair wheels sink into it and you cannot move! You don't even have to sit in the chair before it has sunk into the mat. WAY TOO SOFT! JUST USELESS AND IRRETATING!
The shopping experience was good the price was right the delivery was fast the product is a little flimsy however. I wish it was a little more rigid. it has a tendency even on sort knap industrial carpet to migrate then buckle up against the desk legs.
Purchased for my home office on medium pile carpet. After 2 days of use there's cracks starting under the wheels of my chair. I'm under 150lbs and use about 6 hours a day. Quality is definitely not worth it.
