I've slept on the floor for 3 nights already, and turns out it makes me not need as many hours of sleep.
Did it on top of a rug and two blankets, then another blanket on top. I feel like the hard surface fixed my posture a bit.
I woke up fully rested after years of poor sleep. The only issue is that the floor is cold, and you need to insulate properly.
Anyone tried this and had good results?
