Is it better and easier to sleep on the floor or sleep on a bed?

I am thinking if it’s easier when you move from place to place, if a room is more spacious if you get rid of your bed or if this is not the case. I suppose sleeping on the floor is extremely uncomfortable. Just sleeping on floor vs mattress I am wondering which is better in the long run. I wonder if there is actually benefits for sleeping on the floor. It’s probably cheaper.
