Where can I get one?

Lol I would’ve wanted one as a kid

I want a kotatsu so bad, you can buy them on amazon. the table is its own thing. its a table with a top that comes off and then you put the comforter(which you buy separate) underneath the table top. The couch is its own thing too. But you can buy the whole table or just the heater and get an ikea table and build your own!
