I'm allergic to dustmites (keep waking up with swollen face, itchy eyes, and can't sleep well, and get asthma as well sometimes) and was thinking of investing a duvet for my bed. My partner sweats easily so I need recommendation as to what kind of duvet to get. He says feather duvet we have now helps him sweat less than hypoallergenic ones. I would appreciate any suggestions. And also, does any other couples use separate duvets? I hate pulling match in the middle of the night and so I was also thinking of getting a single duvet for us each?
