Second set of these, first set well over 10 years ago from QVC and the demo on QVC stressed the need to put these in the dryer for 20-30 minutes when they arrive and currently the packaging still says that and the dryer step is the difference between the best pillow you will ever experience and an awful pillow you won't sleep on. They arrive flat and after putting in the dryer they fluff up about 4 - 5 times their arrival size and stay that way. And they will actually look a little to thick but just put your head on them, theyare not too thick, they are perfect and you head will be cradled in comfort and suppored. My old set actually is still holding up well and has undergone may machine washes and dryer runs and the new ones are the same great quality and after putting them in the dryer the same best pillow I have ever seen. And you don't have to keep putting them in the dryer to maintain the fluff, just first time mandatory then when you wash them one or two times a year if you want to. They do come very thin and deflated and would be awful to sleep on that way, the magic is in putting them in the dryer first. If you put them in the dryer first you will be like all the 5 star reviewers in awe of the best pillow in the world. If you do not put them in the dryer before using them you will be baffled at what everyone thinks is so great about the awful flat uncomfortable pillow, up to you, go by directions and be happy or ignore the instructions and miss out on the best pillow you will ever sleep on. I have neck issues and will never use another pillow and the new set are on my bed and the old set are going on the guest bed as they wash up well and are still good. Easily 10 plus years of use with washings. And I also want to say that there may have been someunrelated political news about the founder on news stations and I am not in alignment with those views yet here I am doing a 5 star review and I don't write reviews on 10% of the things I buy on Amazon,but was so happy to see these on Amazon. Thus, I assure you, the product alone is what drives this 5 star review. Please keep making these pillows My Pillow! But please do look at the package and put them in the dryer for the best sleep of your life.
