Please explain me the meaning of the following sentence. (Is my question correct?)

  • I prefer this chair to the other one. It’s more comfortable.

Where does ‘It’ refer to? (Is my question correct?)

Best regards.

What does ‘it’ refer to.

it = this chair.

Thank you very much.

But I don’t understand the meaning of the sentence.
Maybe he or she stood up and somebody else sat down.

No, it’s a simple comparison between two chairs.

Thank you for your time and attention.
