The mat came in a day. No box it just had a sticker. That's OK because it's tougher than any packing material. I didn't think I had a high pile carpet but it does have a thick underlayment. The old mat just disintegrated but this one probably won't.
I like the change in the cleats on the under side much better. The old style was painful (literally!) to put down and pick up but this design is much better. Also the mat seems more flexible. I've only had it for about a month but so far it is superior to the last chair mats I've used.
This mat is just ok. For it being classified as for High pile carpeting I so much disagree. I think it should be rated as low pile. It does not have very long spikes or fingers to dig into the carpeting. It has very low spikes and are kind of crisscrossed. The mat itself is not dense enough for the chair with rollers that I am using on it. It needs to me a thicker vinyl. I am really not pleased with the quality of it. The size is just perfect tho. I am just not very happy with it.
I bought these for flat pile carpet. So thin the chair was indenting into matt. I am using as a floor runner instead. I purchased another one from elsewhere.
