I love these pillows
Size: Queen (Pack of 2)
These are so comfy. I love them. They have made my life so much better.
I have really bad insomnia. I was also getting neck pains from my old pillows.
These are just the best for sitting up and sleeping. I can not tell you how much these changed my life.
They are worth a shot if you are looking for something.
10 out of 10.

Pillows not exactly down..
Size: Queen (Pack of 2)
I just got the pillows the tag say 80% polyester and 20% inner filling and 70% down and 20 % feather + ? Outer filling.. which is not what is advertised in the title. However AI indicated most pillows are constructed with two layers because of it is all dow it will be flat ... anyway the pillows will be tested after tomorrow as they recommend to leave it for one day before using it..

Very comfortable and supportive.
I really am quite amazed with these pillows. As with most people who suffer from neck and back pain it's almost impossible to find a comfortable pillow. One year I must have went through 20 sets trying to find the right pillow. I received these and they were flat in the package. All you have to do is take them out and fluff them up a little bit with your hand and let them sit overnight. What's really nice about these is they are soft and cushy but they have a support that does not flatten when you lay down. Of note when I was looking for pillows, I noticed that these had a price of $110 which was crossed out and then a huge discount. Looking at the item now I see that the top price for the king size is $42. So I'm going to say that $110 was a comparison of what a good pillow might cost. I do want you to know that a set of pillows that I had been using were $200 a piece and these are very comparable to that. I am not having any issues overheating with these as I have a very nice cover on them. They are washable. My neck feels totally better. So all in all I am quite impressed with these pillows and very surprised that the first set I ordered is working perfectly for me. I am a side sleeper and needed my neck to be straight and these do the job with a nice little cushion on them.
