>>15422626You need to understand the context of this joke
Polka is from japan and live in tokyo, japanese people live in really small houses and apartments, and the situation is worse in tokyo where most people live in 1R apartments, which is just a small room with a even smaller bathroom and kitchen, even the people with a good income at best can afford an 1LDK apartment.
The point of this is that you don't have space in your apartment for anything big, so japanese people use futons, that they normally store in their closets or storage to save space during the day, people with money normally own their one single size bed, but people with a lot of money own a king size bed.
She is flexing her money, it's like saying that you own a sport car while the other guys drive a small city car
