I like this image because of the curve,Close up, and high contrast. It makes the image details stand out a lot. And mostly the chair is focused which is shallow depth of field. This image is also a medium shot which helps make the details more visible. Such as the scratches in the chair.
This is a close up. In a close up we see only part of the subject but there enough to be able to identify it. In a medium shot we see the whole subject and a little of the environment.
