night shirt becomes a cushion

This was a night shirt that had seen better days so I turned it into a cushion cover for the desk chair,

The chair has a broken seat where I stood on it to reach something one day. I'd like to get it mended, but it would need to be someone within a reasonable taxi ride as the chair is an old-fashioned office chair rescued from being thrown out where I used to work. It is very heavy and not on casters. With a large cushion the chair is still usable.
