Two men share a single chair, their arms around each other.

He sat on the single chair and she stood behind him.

He sat in the single chair by the table and sighed.

A single chair sat out in the middle of the room.

Instead, she waved him to the single chair, then sat down on the bed.

There was a single chair with a newspaper on it.

He kicked the single chair toward the bed and sat down.

Some of those places are so tiny a single chair is all they want.

He sat down on the bed and indicated the single chair for her.

Because he wanted her to, she took the single chair.
