Why can't people sleep on the sofa?

Many people like to sleep on the sofa in the living room, and home is a relatively relaxed place. They don't want to go anywhere when they are asleep on the sofa. It is worth noting that the top of the beam is the most taboo for us to sleep, but there are not a few people with beams at the top of the living room. If this happens to our own sofa, we'd better not sleep here, which will make people feel depressed and difficult to achieve.

"sofa" is a foreign word, transliterated from the English word sofa. This is a multi-seat chair with cushions. An armchair with springs or thick foam plastic and armrests on both sides is a kind of soft furniture.
