Usually, thermal image of furniture is not very interesting except when used, with mecanics or some preparation inside.
But, with this thermography of an office, we can impersonate a bit Sherlock Holmes.
We can try to interprate the image, the office is in the back and we see two pairs of feet meaning that chair is a rotating one.
Footprint indicate that the one installed weared no shoes and was quietly leaving the chair due to the force of the thermal print.
Position indicates that he was working on the side of the desk not on it and was not using computer in the back who's cold.
Last bot not least, the guy was probably right-handedness because only the left armrest was hot meaning that was lest still and the right one used for work.
