Transition question! And recommendation please
So ive started out on my journey with an IKEA 4 inch futon and did that for quite a while then found this sub and invested in a zonli 2.5 inch i was on that for a while probably a month and through the month having a hard time getting used to the hardness (i already struggle with sleep issues sometimes and im a sidesleeper) also i realized that these things must be maintained i freaked out thinking it had mold or something.. now im sleeping in a conventional mattress in the interim but i dont want my body to get used to it.
Ive been doing some research on the used marketplace and found a futon by the company called karup and this futon is 5.3 inches. I also am looking into a FULI futon but this one is 2 inches and i fear that ill have the same issue so i was thinking i can put the fuli on top of the zonli? Will that be hard to maintain them both?
I need help deciding what to do if anyone has any recommendations please ! Or some advice?
Is one thats 100% cotton very necessary? I really wanna make a good investment Im in NYC btw so the market is pretty good for this
