Yes, you can certainly use carpets on hardwood or tile floors. In fact, carpets serve as an excellent addition to these hard flooring surfaces, adding warmth, comfort, and style to your home decor. Carpets provide a soft surface to walk on, reduce noise, and act as a protective layer for your flooring. Just ensure that the carpet is compatible with your flooring, and use a rug pad or non-slip underlay to prevent the carpet from slipping and protect your floor from scratches.
