I recently had bamboo floors installed in the my office and purchased this floor mat so I could still see the floor while protecting it. That is exactly what I got. It is large enough so I can move my chair to reach the file cabinet and easily enter and exit my desk. It also lets the beauty of my new floor show through.
I ordered a chair mat for Low Pile Carpet from another source and it works great. I recently ordered a few more from Staples and we sink into the carpet. It seems that the chair mat is not sturdy/ thick enough to prevent the rolling feet of our office chairs from sinking into the plastic making it difficult to roll.
It is fine and because they had none in stock they put an order on the internet and it was delivered by parcel post at no cost to me. That was great and it came the next day or so. It looks great on my rug. The people that helped me were very good.
