At this point I am thinking about buying one of those and fit it under the window. Actually I might use 2 of 4" dia pipes bolted vertically to match the mattress thickness. In extreme situation computer fan mounted on the end should help.
Maybe I also will get 2 or 3 pipes in 3/4" dia and drill similar holes, to fit it under end of the mattress. That will add ventilation directly under the "wet" end and give us raise in pillows area as well.
Obviously for full winterizing -covering the window with insulation will be the must, but I don't plan to go that far/cold.
What you guys think?
