It took several days for the Chair Mat to uncurl and lay flat. Chair Mat was flat in store - curing occurred during transit while rolled-up in my car. I recommend rolling "bottom in" such that the curl can be managed by placing the chair or other heavy object to assist with uncurling.
For some reason I failed to notice the short pile carpet in our home office was beginning to show failure in the underneath padding. I shopped the internet to find what is available and found the plastic type chair mat. It is helping keep the condition from getting worse. Now the chair moves ever so easy on the new pad which is a bonus
This chair mat that I bought in the Frazer Pa Staples is of great quality. it protects my carpet and is easy to roll my chair on. The good folks at my Staples did a amazing job by telling me that this was a great chair mat. I would buy this again without any hesitiation!
I purchased this matt 3 years ago but didn't know what kind it was to replace it. I went through records from 3 years ago to find the receipt so I could order the same one. I found it ordered it and very happy.
