I bought a basic clear plastic chair mat for my home office and its working out well. Wish I had invested in one sooner. Would have spare my carpet from unnecessary ware.
This mat protects the carpet under my work-at-home chair. I needs replacing about once every 5 years or so. It protects that carpet and lasts quite a long time.
bought floor mat as working more from home and need to protect carpet from chair wheels but the mat is after a week showing grooves from wheels I don't know how long it will last. S
