When I first came to US, I was amazed to see that "futon" has evolved somehow and did not look like Japanese original futon.
The original futon bedding is just mattress and blanket. No frames whatsoever.
I guess the idea of futon was to live efficiently in a small country/small house.
Futon is foldable. Traditional house rule is that you have to fold your futon and put it in a closet when you wake up in the morning. You pull it back from the closet when you go to sleep. In that way, you can keep your futon clean and use the room for something else during the day.
Living in a smaller house is one way to reduce our carbon footprint. Futon will fit nicely in a small house and help you use the space efficiently.
Do you really need one of those pesky “beds” taking up space in your home?
