When I asked customer service where the chair mats were she said what size. I told her and she said I have one that size right here behind the desk.. I purchased the one she had and flattened it at home for 2 days and put it at my desk. I think I bought the wrong one because it is very hard to roll my chair. I have to get up to move it. But I used it already so I'll deal with it.
This floor mat developed divets where the chair sits within hours of normal usage. The plastic is not hard but somewhat maleable and so is difficult to roll on. I would not recommend this item. Considering returning since it’s useless but just don’t feel like the hassle. Not a good quality product.
It's almost impossible to move an office chair around on carpet in your house so while everyone is working from home now you need to buy one of these. Good price and delivered right to your door.
