This product does not move once you put it down. That is the one thing I really like about it. I would recommend this to anyone but just be careful handling because it will stick you and it hurts alittle. I guess that is why it will not move. I think the price is somewhat high.
After much looking - and waiting - this mat finally makes the grade. I can't believe there are so many mats that claim to be for pile carpet which would barely be useable on berber. My chair wheels with my 225 lbs atop don't sink into the carpet through this mat. The points on the bottom are kind to the flesh as well.
Bought this to go over carpet so my chair would slide - The chair slides but so does the mat - It does not have any nub grippers on the bottom - Terrible design
This was the cheapest mat I could find. After about a month the wheels on my chair are putting a groove into the mat and I can see it already starting to crack. Very cheap then again I'm not going to spend upwards of [$] (that others were going for) for a piece of plastic.
It's a chair mat. Works good looks good. Bought two then ordered two more yesterday. Came with a half curl in a box but it lay flat with the curl on the bottom.
