Sheldon’s Spot is a place in Sheldon and Leonard’s apartment which Sheldonhas claimed as his own. In his own words, Sheldon has placed this location “in a state of eternal dibs”, and has little tolerance for anybody who tries to sit there. Specifically, the spot is the left side of the couch, but was also seen as his spot in the flashback episode “The Staircase Implementation”, in which the first furniture seen in the living room are simple lawn chairs.
Sheldon relates his spot to himself in mathematical terms in “The Cushion Saturation”:
- “In an ever-changing world it is a single point of consistency. If my life were expressed as a function on a four-dimensional Cartesian coordinate system, that spot, at the moment I first sat on it, would be (0,0,0,0).
