Sheldon's spot is the position on the couch he has claimed as his own, putting it in a "state of eternal dibs". Sheldon has described his spot as the "single point of consistency" in an ever changing world. Sheldon has said that if his life were expressed as a function in a four-dimensional Cartesian coordinate system, his spot, when he first sat on it, would be "0,0,0,0" ( The Cushion Saturation ).
