What chair did lily tomlin sit in Saturday Night Live and what character she portray?

Lily Tomlin was famous for her character "Ernestine", the cranky and sarcastic telephone operator, on Saturday Night Live. However, she didn't have a specific chair associated with the character.

Ernestine's most common props were a headset and a vintage telephone. She often sat at a desk with a phone and a microphone, but the type of chair was not a consistent feature of the character.
