Greetings, We have purchased covers for several pianos in the school at Vanderbilt, and they are invariably left off. Even the two padded covers for the concert instruments are usually found piled in the corner. I don't think I would advise trying to keep covers on anything but the stage pianos, as the students just don't have the instrument awareness here to use them. Good luck, Ed Foote Nashville, Tn.
