Wondering if there’s anything I can do about this. I live in an old stone house and while ventilation could be better, I do open my windows every day (and leave them open as much as possible) and have a dehumidifier on the go. However in summer when it’s humid my sofas and scatter cushions sometimes feel damp. Like when you’re on holiday in a humid country and outdoor cushions feel damp to sit on. It really bothers me - is this common? I don’t remember it happening in previous houses, and I’m not sure what else I can do.
