Many Japanese people use this traditional table which is called Kotatsu こたつ.
The table is covered by a thick blanket like in the picture above.
About Kotatsu
A kotatsu is a traditional Japanese table used during winter which has a built-in electric heater.
Cheap kotatsu (75 × 75cm) costs around 7000 yen like in these photos. (not including the blanket) Of course, better quality and larger ones cost more.
We place our legs under the Kotatsu while sitting on the floor.
Once you sit in Kotatsu, it is hard to exit from it, because it is really comfortable.
I sometimes spent nights lying under the table.
However, it is not a bed, and I realized I had slept all night long in Kotatsu.
I don't recommend to sleep in Kotatsu for long hours, because sleeping long periods in Kotatsu makes our bodies sluggish and tired.
Nevertheless, sleeping in Kotatsu is nice and warm. I can't stop using Kotatsu during winter.
If you use a Kotatsu you can save more money on electricity than using an air conditioner or an electric heater.
In Japan, many furniture store sell Kotasu mainly in winter.
