Excellent buy for the money. A bit softer than it should be so that moving chair around is not as smooth an effort as I would like. Nevertheless I am satisfied.
Ideally a thicker pad would be better The carpet and pad are at least 1/2 inch thick but so far this pad is working. The question is how long will it last?
It works but it's not the best for my carpet. The wheels create dents in the mat that make the chair a little tougher to move. Still beats trying to roll the chair on carpet.
