The overall size (width and length) is good but the thickness is not ideal. When sitting in chair on top of this plastic protector the sides come up and do not lay flat on floor or carpet.
This mat was perfect for my hard floor. It flattened easily (my biggest concern) and is all but invisisble on the floor. This was an excellent purchase.
Since I have carpet in my home office I needed to put down a mat-like item underneath both office chairs (one at the computer and one at the desk). Putting this chair made sitting at both places much easier. Be careful of the back as you are putting it down as the grippers are sharp but once it’s down it doesn’t move too much because of those grippers. Very reasonably priced too - it will protect the carpet which is so much more costly to replace!
Ordered this chair mat online and it came in two days. It came flat not rolled up so I was able to lay it flat. It was a perfect size for my granddaughters desk today. Would recommend.
