The therapist is using a technique known as the empty chair technique.
On the chair, you imagine a person experiencing conflict. Or imagine a part of yourself. Then talk to the empty chair. Describe your feelings, thoughts, and understanding of the situation.
Chair exercises ask you to move between chairs that represent different perspectives or parts of yourself. For example, you can use two chairs to represent the parts of your behavior that you want to change and the parts that you don't, or the "reason" and "feeling" aspects of yourself.
Although a spontaneous approach, the mood of the treatment may not be suitable for all clients and may even be overly aggressive for some. Also controversial is the lack of oversight during dialogue.
