Ok, not for everything. I was thinking about how hot my office chair gets and how to avoid the sweaty back syndrome. The chair is oh so cushy (good) but I am not sure the same level of cushiness could be maintained if ventilation was added so I was thinking why not a cooled chair? My folks have a Volvo and nice as it is my favorite part (in the winter at least) is the heated seats if it works for warming a car seat then why not cooling an office chair? Well I’m no engineer but having tinkered with computer overclocking and modding I have toyed (a wee bit) with peltier coolers and it seems to me that a combo of water and peltier cooling could make for a pretty comfy chair… though I could be wrong.
