Four hands means two therapists attending one client at EUR 360 an hour; the name counts hands, though in body-to-body the working surfaces are far larger than hands.
Four hands is a count, and a slightly misleading one. The phrase comes from conventional massage, where a second practitioner simply brings another two hands to the table. In body-to-body the tools are forearms, thighs and torsos, so the arithmetic undersells what a second therapist brings: another body's worth of contact, working in the same moment.
Two therapists can work in mirror, one on each side, so both halves of the body receive matched pressure and neither is left waiting. Or they can work in relay, one travelling the length of the back while the other anchors the legs with steady weight. Most pairs combine the two. Usually one of them leads and the other answers. The office matches therapists with shared hours behind them, since a pair that has never practised the handover leaves gaps a client can feel.
Four hands is one client. A couple who each want a therapist are booking something else: two parallel sessions sharing a room.
Two therapists bill EUR 360 for each hour. A two-hour pairing totals EUR 720 and sends EUR 360 in advance; a three-hour pairing totals EUR 1,080 and sends EUR 540. Every two-therapist booking carries that deposit, whoever the client is and however soon the start, because acceptance closes two calendars at once. No overnight is priced for a pair.
The room needs a bed that can be reached from both long edges. The four-hand page shows the pairings, the journal on four hands examines timing, and the deposit entry explains the advance.
