| Some issue with bringing this design into today: - air quality (especially if closed off), less air volume means the air gets bad faster - air humidity, raises faster through sweat in a cupboard setup, for the same reason the inner tent of good tents tends to be made of a fabric which allows air humidity to go out of the inner tent (I think, haven't bought a tent forever) - fungus mainly due to the higher humidity/reduced ventilation the chance to have a fungus infection in your box (and also/especially the bottom of you mattress) All of this where issues back then too, just so much smaller then the risk of freezing. A risk we currently tent to not have in apartments due to better heating, insulation (even on non insulated housed due to better closing windows and better thermal isolating glass). Not being in a short little ice age also helps. Capsule hotels are somewhat of an modern version of this. They tend to have some form of AC in every capsule to fix the air quality issue and hugely reduce the humidity and in turn fungus issue If you are stuck in a situation where idk. heating is broken and its dam cold creating a similar setup by e.g. butting a tend on your bed can still be a grate idea. |
