sleeping on a cot bed with a stove going is warm i sleep on my cot bed with just a 3 season bag no sort of insulation on the cot bed. by sleeping on the cot bed it raises you into the warmer air and the air below the cot is like a cold sink witch keeps the cold air away from you. I know you like Wiggy Andy but seriously try sleeping on a cot bed with the stove going then form you own opinion.
Hi Karl. Actually I have - both the US Army cot and the luxurylite mesh cot. Problem is not when the stove is running, but when it goes out, as the ultralight ti or ss ones will do overnight unless you have a stove guardian, feeding it every hour or so! The sollid cast iron ones that'll burn for 6-8 hours or so on one load are a different matter. And when the stove goes out ,you are back to the problems of cold floor and air under the cot issue, as snowy's post points out.
As Paul also points out, the size of the tipi is also important, with smaller being better for heat retention. The Polish lavvu for example will keep you toasty all night with just a candle-burner going!
