Adding cooling and heating to chairs is one of the better ideas, they provide a lot of surface area close to the body making it the most energy efficient solution potentially, a major obstacle is powering it, with current battery tech I imagine needing to change it regularly needing more than one battery making it expensive and decent office chairs are already heavy, with all these additions it could be impractical in some situations, perhaps with some wireless energy transmission?
