>>2649707It's honestly not great, but as long as you have a foam pad it's usable.
A better solution is just a folding tatami matt and a futon mattress. That's my future goal.
You can fold up the tatami and futon when you want to use the space for something else.
You can also just put a mattress on the floor and flip it against the wall during the day.
Just remember you need to let the bottom air out.
