Not really. The lady who used to live on my couch bought a Japanese futon in an attempt to stop living on my couch, and my sister used to live on an American mattress sans frame and they’re wildly different things. An American mattress is 2-3x the thickness of a Japanese futon and while it’s less comfortable without a frame, you can comfortably live with it on a hard American style floor. A Japanese futon is insufficient on an American style floor and really needs the soft springy surface of a tatami floor.

It’s the difference between a support and comfort structure vs a person sized cushion

Wikipedia futon:

A complete futon set consists of a mattress (敷き布団, shikibuton, lit. "spreading futon") and a duvet (掛け布団, kakebuton, lit. "covering futon")

However, Western-style futons, which typically resemble low, wooden sofa beds, differ considerably from their Japanese counterparts.[1][16] They often have the dimensions of standard western mattresses, and are too thick to fold double and stow easily in a cupboard. They are often set up and stored on a slatted frame,[13] which avoids having to move them to air regularly, especially in the dry indoor air of a centrally-heated house[17] (most Japanese homes were not traditionally centrally-heated[18]).

"Western-style futons" don't really sound like futons at all tbqh.

Futon are made from sheets of wool (traditionally) or cotton (modern) folded over several times and then tied together. They’re very soft and fluffy but can get flat as used. Daily folding and putting away of the futon helps keep them fluffy.
