I've recently starting sleeping on the floor of my room as an experiment to see if, once I move out, I would be ok with replacing a traditional bed with a foldable futon full-time. For the last week I've been sleeping on a makeshift one constructed from a thin foam egg-crate and a 1" camping pad covered with an old comforter. Total thickness of the contraption is 3" or less, and the whole contraption can be folded up and stored in the bottom of my closet in less than a minute.
I've only been at this for a week, but so far the experience has been surprisingly pleasant. The first two nights were a bit restless, but I now fall asleep just as quickly I used to and sleep through the night. I've noticed some soreness in the morning, but I'm not sure if it's been due to the arrangement or an unusually hard week in the gym.
I was actually inspired to try this from a picture of a similar arrangement in a very small bedroom, along with some simple math. My family has a fairly large house and bedrooms, yet much of this space is taken up by beds (25% of the floor space in both my own room and my parents room!) This seems like a gross waste to live with long-term if other, foldable options are just as serviceable. It seems that becoming accustomed to this would allow me to live in a space with much smaller bedrooms without losing any utility.
Has anyone else tried or considered this transition? If so, how did it go, an were you able to sustain it long-term?
