To provide a finger-pressure chair to enable to stimulate points on a human back simply anytime, by making a thin rubber sheet into a finger- pressure chair utilizing vibration, by attaching protrusions with magnets inside, covering with cloth, and attaching straps at four corners.

On a thin rubber sheet 2 set in a size matched to a seat back rest of an automobile, protrusions 3 with magnets 4 embedded in positions agreeing with points on a human back are equipped. Protrusions 3 are set, for instance, in a way that 5 protrusions in center, upside/downside, right/left corresponding to one point. The rubber sheet 2 is covered by cloth 5 to which straps 1 are sewn down. This is to be used by fixing it to a seat back rest of an automobile at a head part and a trunk part with straps 1. Thus, points on a human back can be naturally simulated by vibration of an automobile during driving.
