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.
THIS IS WAY TOO THIN. YOU CANNOT EVEN MOVE YOUR CHAIR UNLESS YOU GET UP AND MOVE IT. WE ARE CURRENTLY SHOPPING FOR A MUCH BETTER ONE AND THESE WILL END UP EITHER IN A LAND FILL OR A RECYCLE BIN SOMEWHERE THE BAD THING IS WE BOUGHT TWO.
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.
