Without that I fear utter chaos and, no doubt, serious implications for their well-being.
You haven't acknowledged that it's totally normal in many cultures for people not to have their own beds and to sleep wherever they fancy each night.
I don’t know enough about cultural implications but I guess I’d wonder if that comes into play sometimes.
Doesn’t sound like it with the ops description though.
At one point when we moved when my twins were little we had two double futons down in one room. The kids had been climbing out of cots in the previous house and were still often in our bed nursing over night and we opted for this for ease initially (as needed to buy our own furniture for the first time also).
But it worked we kept it for a year. Just two double futons on the ground, nothing else in the room outside of extra thick mattresses and duvets and pillows. But it worked well because I could nurse both or either and dh could snuggle one to sleep sometimes and eventually they learned to settle without nursing. Eventually we set up toddler beds with a single futon in between so we could take it in turns to settle them and sleep in for a bit if needed, and we set up our own bed in another room. And then they got drawers and toy box etc in there eventually.
But if we kept having kids I would have been inclined to keep sleeping like that. Because it worked out that both me & dh got more sleep that way, without feeling isolated from each other. So if we had several kids spread out in age I could see us keeping a ‘sleep room’.
When I read about cosleeping being the norm in other cultures I kinda wonder if it’s the same sort of set up. And how long it suits them to bed share this way. Because I guess -although the op definitely sounds chaotic -it might not be for everyone whose families sleep this way longer term.
But that’s off topic somewhat.
