Northerners were used to sleeping on the heatable brick bed. Because it was warm, even if a slightly thinner blanket was used, it would not be too cold to get up at night to heat up the brick bed.
However, there were also people who felt that a brick bed was not aesthetically-appealing and wanted to sleep on a bed instead. Of course, those who were willing to spend so much effort and could afford a bed were mostly rich people.
Therefore, the rooms built by the rich were very big. Just the inner rooms alone were about 40 square meters. A large bed could be placed on the northwest side and a screen could be placed to separate it from the brick bed on the east side.
In this way, the master could choose to sleep on the bed or brick bed depending on his mood.
