Tried this myself and can approve it! My back feels a lot better after a week on the floor.

The crazy thing about it is that everyone I told about my experiment said to me: „yeah I already heard of it, tried it and it helped“ 😅

Even my mother is doing this from time to time.

Anyway, I will do this for some more days, but I‘m pretty sure that I will get rid of my mattress in near future.
