this is a very good smaller mat that I was looking for..it was on sale 50% off..who couldn't make that work? On carpet it gives some protection but still works down although not anywhere near working into carpet that is unprotected. It all bounces back after you get up anyway.
This mat is so thin the chair it was intended to help wouldn't even roll! Instead - made deep impressions on the carpet surface it was intended to harden for an easier glide. Like a Republican candidate - if I only wanted to look at it - it was fine. But asking it for substance and to do the job it was intended to do - makes no sense whatsoever! It just sat there having taken my money. Shipping was fast - but again a waste of time since product didn't work. Sadly customer service told me no better (thicker) product was available!
I moved in a new house. I was afraid the chair will mess up the new carpet in the office room. I was happy to find this Chairmat in Staples. The price is low but with the good quality. This is the exact one that I was looking for from the market.
