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.
