A folding seat assembly is attachable to the upright vertical post for a tennis net and consists of a pair of interchangeable clamp brackets secured around the vertical post. An upper elongated tube is pivotally mounted to the upper clamp bracket and is slidably mounted to a bottom seat guide. A lower elongated tube is pivotally connected to the bottom clamp bracket and is pivotally connected to the bottom seat assembly to create a triangular support for the seat. A second seat can extend from the opposite side of the same pair of clamp brackets. The seat(s) are maintained in a vertical inactive position by an over-center arrangement and a detent mechanism.
