how to build the kotatsus

Hello.
This is May in Japan.

Last time, I introduced the kotatsu.
Today I'd like to introduce how to build the kotatsu.


At first,lay out the mattress of kotatsu on the floor.

Next,locate a table frame on the mattress.
The heat source is united with underneath the table frame.

Next, place a coverlet cloth over the table frame.
I recommend that the coverlet cloth is thick, because it is warm.

Place another coverlet over the table frame.
This another coverlet is a cover.
The cover is nonessential but thermal effect is provided.

Finally,put a kotatsu board on the coverlets.
It is the completion of the kotatsu !!

I'll survive this cold winter with the kotatsu.

I'll introduce the caution points of the kotatsu, next time.
