A sheet covering the mattress, then we lying on top, then the duvet covering us to varying degrees of area and precision depending on temperature and activity while asleep. My son snakes over and under the duvet several times along his body.
“Fitted sheet” (sheet with elastic on the corners, a little smaller than a same-nominal-size sheet) that covers the mattress, regular sheet, optional light blanket, comforter, optional quilt or something like that if it’s very cold. That’s standard bedding around here (US Midwest). This duvet-only (not counting mattress cover) stuff is wild to me. May have to try it.
With just one quadruple-thick blanket ('duvet') you are either broiling or freezing, with no ability to peel back or add just one layer at a time. Can't understand how anyone can be comfortable with that.
I usually just stick my leg out. Works every time.
Maybe it's more a question about central heating? The temperature in my flat is in same 3-5 degree range most time of the year, so I only had to choose right duvet once.
