the furniture edition of towers of ilium

I have two glaring deficiencies in my design education and knowledge base: HVAC and furniture. I am aware of HVAC design in a general sense, but I need to find some opportunity to do actual layouts--maybe even calcs. Furniture is a whole other bogeyman. Architects think they know about furniture, but we're actually quite dim. All generations are littered with building design that doesn't consider furniture. Worse, when architects design furniture they do it in complete ignorance of the human body. Granted, for many centuries there was not much in the way of true knowledge of ergonomics, but Architects saw fit to disregard common sense in search of some lofty concept. 

I feel comfortable at the chair I am sitting in now. Maybe I'm deluding myself.
