Want to put indoor/outdoor (commercial) carpet in a room of a house, is underpadding really necessary? I had a room in my previous house that did not have padding underneath and I liked the firmness of it. But would I be better off getting the padding anyway?
Pad isn't necessary. But there is no such thing as indoor/outdoor carpet. Commercial carpet will fall apart if it gets wet continually, like outdoors. The only carpet that water won't hurt is turf. I don't think you would want turf indoors.
