It’s not as thick as I expected so with how plush my carpet is my chair doesn’t roll as easily. BUT it’s better than being stuck in the carpet and not able to move. I’m satisfied.
It may protect the carpet but its thickness (or thinness) allows it to compress into the carpet and thus makes rolling the chair around tough - i.e. the chair casters get hung up in the divots . . . or maybe I'm just too fat!
This is a replacement for an older one which after years of use wore out. I would not have purchased it a second time if I were not satisfied with the product.
Arrived in time - bend like hell. Mat is to thin and moves spikes are way to short to have any effect. Chair wheels dent the mat very heavily - makes moving the chair around difficult at times. Does not work well on thicker carpets. Not worth the money.
