First of all, I am not sure if a very thick or heavy duvet is necessary in our situation. You know, nights tend to be really cold in our flat, and this is especially true when winter comes and the temperatures inside the flat fall below fifteen degrees Celsius. You know, we usually wear sweaters at home and sleep under layers of blankets. But on the other hand, a very warm merino wool duvet will be useless now. It"s the middle of summer and we can"t stand the heat! We are now wearing T-shirts and shorts, and we spond the nights covered in light blankets. The problem is, we sometimes get hot, especially when we are trying to fall asleep. You can imagine how irritating it can be! On the other hand, I often wake up in the morning and realise that I"m cold, even when I"m covered in the warm polar fleece blanket. This is why a light merino wool duvet might come in handy right now. You know, wool is extremely breathable so it regulates the body"s temperature. But everybody knows it"s not cheap at all. This is why I have just decided to get just one set of wool bedding for each member of our family: my husband, my two daughters and me. I guess I will have to find a solution and buy some cheap duvets that are neither too light nor too heavy.
