The material is very thick and substantial. If you have deep carpet and or a heavy chair this is a good solution. The plastic material is clear and vey flexible hopefully it remains this way over the long haul.
The two mats are saving a lot of rug lines and dirty rollers from messing up the wall to wall in both offices in my home.very good price and great with a bumper out front for my feet plus roll around space!would recommend highly!
