Only if they are fitted with inexpensive and low-quality wheels that ruin your flooring would rolling chairs be bad for your carpet. There are two important things to bear in mind with regards to this. Firstly, the type of the wheel itself. If the wheels are not good enough, they don’t roll well and pull on the carpet when you move the chair. Secondly, you have to consider the quality of the carpet. Even a not-so-heavy person in an office chair will create 100 psi of pressure from the chair on the carpet. This is enough to ruin soft carpets. On the other hand, heavy-duty carpets can easily survive this kind of pressure. Amongst the top brands you can consider include Herman Miller, Steelcase, Humanscale, Hon, Haworth, Knoll, and Office Master.
