The mat fit easily under my computer desk. However unrolling is was a little difficult because the plastic is stiff.The mat became flat after several days. Based on past use this will save my rug and make working on the computer easier.
Maybe my carpet is too plush but it's not high end carpet. My chair leaves impressions in the mat sort of like little pot holes and it's hard to roll out of. annoying if you are trying to just scoot forward a few inches closer to the desk because the chair wants to roll back into the cup it created. The impressions in the mat come back out but it's a little annoying
As a chairmat for chairs it is only usable on commercial grade carpet. Any carpet with high pile will cause the chair to sink into the chairmat. Your home's carpeting most likely will be too thick for even this chairmat and you will get "stuck" on your chairmat from the wheels sinking in to the chairmat. Move up to the next grade chairmat It will be worth it. This chairmat now sits under the cats' litterbox to keep the mess from spreading.
Purchased 6 of these for the office staff after the previous ones began crumbling. I wanted something thicker than the previous and they seem to be working very well.
