It solves the problem very well.   It protects my mid-pile rug from shedding and prevents denting.   It is quite clear and looks great on the rug.   I got the smaller size and use it between two desks in an L-shaped configuration.   It works very well with my 5 roller wheel desk chair.   It came relative3ly quicking considering that it is made in the UK.   The plastic is nice and thick to prevent bending and yet surprising thin for it's strength.   This is very much a miracle plastic.   This chair matt was the best from Wayfair was the best I could find on the web - and I reaslly searched.
