Abstract: The invention is an arcuately reciprocating human sexual fitness machine having male and female seats from which the female occupant may pivot and reciprocate along an arcuate path forwardly about a horizontal axis toward and away from the other seat, and may also reciprocate along a horizontal path. Counterbalancing of the female seat provides a levitating effect as the seat pivots forward. The machine provides a device for a male and female couple to engage in intercourse while both are seated, and able to be in complete and uninterrupted frontal contact upwardly from the genital region. The female seat is provided with an integral upper high restraint, a remote abutting surface for contact with the occupant of the male seat and is bifurcated to produce an open center for sexual access with a sitting surface forward of the horizontal pivoting axis of the seat.

Abstract: An intimacy chair assembly and method to assist a human couple to engage in sexual intercourse with reduced effect of gravity or the reduced expenditure of substantial energy including a pair of facing seats for the couple, the assembly being capable of reciprocating movement of at least one seat selectively continually toward and away from the other seat in a substantially longitudinal direction and of selectively continually pivoting said one seat about an upright axis.
