  • Patent number: 5720518
    Abstract: A universal bike seat and exercycle seat cushion that is placed on top of conventional bike seats, having two separate matching cushioning devices whose surface area is smaller than the conventional bike seat upon which they are placed allowing unlimited placement adjustment options for the rider. The cushioning devices have multiple stages of cushioning materials including low density open cell foam, high density open cell foam and low density closed cell foam, and are semi-oval in shape, which creates a no-contact, `pressure-free` zone for the rider's tail bone, soft tissues and genitalia. The device may be secured to the bike seat by appropriate means, such as a slip cover.
