The staff person in the chair that's on this mat rolls from desk to file cabinet on the right and to the printer on her left; she needs coverage and this mat is wide enough to do it.
While I have a different Staples mat at my computer I purchased this one for use at my sewing desk. As the item description says it works best on an unpadded commercial carpet. While it is a little light weight for where I have it it is providing adequate protection for my carpet.
Purchased this chairmat to replace a perfectly good one which I had but chair rollers dented (settled into) the mat making rolling difficult. The replacement which I paid two and half times more for offered not better support for the chair wheels on the same carpet. The carpet is a dense weave and should have been o.k. for the "plush" model chairmat.
WHEN i SAW 1.3 " i CERTAINL DID NOT EXPECT IT TO INCLUDE THE SPIKES. Most carpet mats are rigid and do not indent when parked. This mat is for thin rug and padding. You know it!
