Lorell Chair Mat for Medium Pile Carpet, Rectangular with Lip

Finally, a mat that stays in place on carpet! We bought this mat to replace the one we had that seemed to "travel" every time my husband rolled his office chair backwards. The plastic spikes on the underside of this mat are longer than what I've seen with other chair mats that were also supposedly for carpeted floors, and that's what makes it stay put better. We also liked that it came in the larger size (45x53) , instead of just the normal 36x48 we tend to see in the stores.

Nice and thick yet tapers on the edges. Is doing really well on our carpet. Easy to unroll. For the price, I wasn't expecting it to be this heavy and nice.
