my back is broken?

hello people,sorry for the exaggerated topic but after days of wondering what to write i suddenly realized something that has( i maybe wrong) never been said before.

we all have been experiencing sore backs for not sitting straight or sleeping the right position and sometimes we blame the chair or the bed or whatever it is.I'm not suggesting we blame ourselves for the pain but as of right now,I'm sleeping at my friends house for a while and i always make the couch or the floor of his living room as my bed.thankfully i haven't suffered any pain on my back but i just realized the "goodness" sleeping on the floor/couch is,i meant not physically but rather mentally.
You see, as we feel uncomfortable sleeping on the floor/couch, it has made me realized the satisfaction one can get by sleeping on a bed. think of it as a homeless person given a bed for the first time.I'm sure in the past he has slept in a comfortable bed but after so long sleeping beside the road,he can finally get a bed after so long.The satisfaction of it just makes you more grateful of having a bed.
Some of you might say that I'm just rambling my @$$ off on this but just have a thought on what would have been if you weren't born in the same circumstances?what if you were born in a place were we sleep on beds with nails as our mattresses? see what i mean? you can never enjoy much of your time sleeping in bed until you have slept on a couch/floor. my advice?try sleeping on the cold floor once in a while then just think about it(not recommended for people with bad backs)
