Every night was a battle. Quite literally a battle of the duvets.
The crux of the matter is that I like to be super cozy at night under a nice heavy tog and my husband has a core temperature close to that of the sun.
Every duvet we tried claimed to be temperature regulating and breathable but still didn't solve the problem.
When you have two different people in a bed, they generally have different temperature requirements so why would you have the same tog weight on both sides?
he Addition came into it's own. A section of duvet that fits over one side of the bed making one side of the bed warmer than the other. The main thing is that it works with your existing duvet.
