After discovering dust mite allergy, I replaced all my bedding with allergy proof products including these pillows from Mission Allergy. They are super comfortable, soft yet firm enough that my head doesn't sink to bottom. They holds their shape really well and are easy to re-fluff. My old pillows may have been my biggest culprit. After switching to these new pillows and encasings, my symptoms improved immediately. After first night, no sneezing, stuffiness or itchy eyes. All the products I got from Mission Allergy are great quality and well worth the investment!
