An extendible chair, comprising:
- a stationary frame including two vertical side members defining a cross-dimension, each said member having a back end and a forward end;
- a seat portion having an upper surface and a lower surface, said lower surface pivoting on and about a forward end of said stationary frame side member;
- and
- a back rest member pivotably coupled rearward to and within said stationary frame, said back rest member pivoting downward toward said forward end of said stationary frame.
