The mat itself I will give a 5 star rating. It was rolled when I picked it up but the salesman (Evan) assured me it would flatten overnight. And it did. My reason for a 4 star rating is the tape that was used to keep it rolled. It did not remove easily and left a very sticky residue along the entire tape line. I will try rubbing alcohol or Goo Be Gone. I’m sure either of those will work perfectly but just annoying it has to be done. Use twine or a different tape. I would recommend the mat but would share the post sticky residue removal process.
The plastic is too soft so the chair sinks into it rather than glides across it. Only slightly better than having the chair on the carpet. Spend more money and get a better one.
