Abstract: A seat cover for an rowing machine seat has a top for overlying the top of the seat and a skirt extending downward from, and running lengthwise along the length of the perimeter of the seat cover top. A cord that is spaced below the top piece runs along the length of the skirt and has a first end that protrudes from one of confronting lengthwise ends of the skirt and a second end that protrudes from the other of the confronting lengthwise ends of the skirt. The cord allows that skirt to be drawn around the seat for holding the seat cover in place on the seat. An open-top pocket hangs from the seat cover at a location along the perimeter of the seat other than the location at which the opposite lengthwise ends of the skirt are in confrontation. An electrically powered personal device, such as a battery-operated entertainment device, can be placed in the pocket for use by a user of the rowing machine.
