The empty chair technique: what it is, and what really happens.

Most people meet the empty chair technique in a film, a psychology seminar or a half-remembered anecdote: someone shouts at a piece of furniture and weeps. That is the caricature. What actually happens is quieter and stranger — you say one plain sentence to a chair, and your own voice gives you away. I am a psychologist and Gestalt therapist working online, and this experiment comes up in my practice most weeks. Here is what it really is: where it comes from, how it unfolds, what it can sound like, and where its limits are.

What the empty chair technique is

The empty chair technique is an experiment from Gestalt therapy: a chair stands opposite you, empty, and you speak to someone as if they were sitting in it — a person from your life, someone who has died, or a part of yourself. Often you then move into the other chair and answer from that side. That is the whole mechanism. Everything else is timing and consent.

The point is not the chair. The point is the shift from talking about to talking to. “My father never asked how I was” is a report: safe, finished, and it changes nothing. “You never asked how I was” is an address — it happens now, in your body, in the present tense. And what is present can move; what is only described stays exactly where it was. Gestalt therapists call the residue of such conversations unfinished business: the things never said, often to people who are no longer available to hear them.

Where the technique comes from

It is most associated with Fritz Perls, who made it famous in the 1960s, though its roots reach back to Jacob Moreno’s psychodrama and the idea of role reversal. Perls took the theatre out and kept the encounter. Gestalt therapy itself was developed in the 1940s and 50s by Fritz Perls, Laura Perls and Paul Goodman — what Gestalt therapy is and how it works is the longer story, and the chair is only its best-known moment. It is one of several experiments: I have also written about the seven Gestalt therapy techniques I use most.

Empty chair or two-chair dialogue — the difference

These two are constantly mixed up, and the distinction is worth having, because they do different jobs.

The empty chair is for unfinished business with another person: the parent, the ex, the boss, the friend who left. The chair holds them, and you say what was never said. The two-chair dialogue — also called two-chair work, or simply chair work — is for a conflict inside you: the part that drives and the part that is exhausted, the inner critic and the one being criticised. You take both seats in turn and let them speak to each other. Same furniture, different geography: one crosses a distance to someone else, the other maps a split within.

How a session actually unfolds

None of this is a script, and every step is offered rather than instructed. Roughly, though, it moves like this:

1. 1

   Something arrives on its own.

   I don’t start a session planning chair work. It shows up — you are telling me about a conversation with your mother and your hand makes a small pushing gesture, or a sentence stops halfway. That is the material.

2. 2

   I ask, and you decide.

   “Would you be willing to try something?” If the answer is no, that is a complete answer and we keep talking. Consent is not a formality here: an experiment done under pressure teaches you only that your no doesn’t count.

3. 3

   The person is placed.

   Who is in the chair? How are they sitting, what is their face doing, what are they wearing? Ten seconds of this and the chair stops being furniture.

4. 4

   You speak to them — in the present tense.

   Not “I wanted to tell him that…” but “I am angry with you.” I will keep nudging the grammar back: to you, and now. That one correction does most of the work.

5. 5

   Sometimes you change seats.

   You sit in the other chair and answer as them. People expect this to feel like acting; more often it is uncomfortably informative — you find out what you assume the other person thinks, which is not the same as what they think.

6. 6

   We stop while you can still feel your feet.

   The ending matters more than the peak. We come back: what happened in your body, what surprised you, what you want to keep. Nobody leaves a session mid-flood.

What it can sound like

What follows is a composite, not a client — nothing from a real session appears on this page. Someone tells me for the third week running that their father “was just like that”: tolerant, tidy, closed. I ask whether they would say it to the chair. They start reporting again — “he always…” — and I ask them to say it to him. There is a pause, and then, far quieter than everything before it: “I waited for you.”

That sentence had been unavailable for twenty years — not because it was hidden, but because it had never been addressed to anyone. Nothing dramatic followed. They cried a little, we sat with it, and the week after they mentioned that the conversations in their head had gone quieter. That is the usual size of it. The empty chair is not a catharsis machine; most of the time it produces one true sentence, and one is enough.

Why speaking to a chair changes anything

Because your body barely distinguishes between addressing someone and imagining them. The moment you turn towards the chair your breath shortens, your voice drops or climbs, your hands look for something to do. The feeling that was safely packaged inside the report becomes present — and what is present can be worked with.

There is a second reason, less often named: the chair is a place to finish. Many of the conversations we carry can never actually happen — the person has died, is dangerous, or is simply not interested. The work of the empty chair is not to change them. It is to let you complete your side, so that you stop rehearsing it at three in the morning.

Does the empty chair technique work online?

Yes — and I say that as someone who works online only, so I have had every reason to notice if it did not. You turn your own chair, use a cushion, or bring a second chair from the kitchen; on video you can simply move to the other side of the frame. The reference point is unchanged: a defined place where the other person is.

Two things are genuinely easier at home. You are in your own room, which means you can speak loudly, cry, or sit in silence afterwards without arranging your face for a waiting room — and when it is over you are already home, with no train ride while everything is still open. What asks more of me is that a webcam shows me less of your body, so I ask more often, and more directly: what is happening in your chest right now?

When I would not suggest it

Chair work is not neutral, and more of it is not better. I do not suggest it early after a trauma, or before there is enough ground between us — with unprocessed traumatic material an experiment like this can overwhelm rather than clarify, and stabilisation comes first. Not in an acute crisis. Not to produce a scene: catharsis for its own sake is not the goal, awareness is. And never as something done to you — if the honest experiment of a session turns out to be saying “no, I don’t want to”, then that is the experiment, and a good one.

What research says about chair work

Honestly: the chair has been studied most systematically outside Gestalt itself. Emotion-Focused Therapy, which grew in part out of the Gestalt tradition, adopted chair work as a core intervention and has examined it closely — particularly two applications: the two-chair dialogue for self-criticism and inner conflict, and the empty-chair dialogue for unresolved feelings towards another person. That is where the evidence for chair work mainly lives. What no study can tell you is whether it is right for you this week; that is a question for a conversation, not a citation.

Curious rather than convinced? That is the right place to start from. The first conversation is free, twenty minutes, and nobody talks to a chair in it — we look at what you are carrying and whether I am the right person for it.
