this pillow does work
For months my neck had been brothering me every morning when I woke up. Figured it was stress and I always planned on getting a massage. But I never did it. I ended up seeing this pillow on Amazon and got it. It was almost an instant 180. My neck pain is gone!
This pillow is stuffed very full but isn't super firm. It's a bit hard to describe. The seams are well sewn and the pillow has held up very well for a week now. No weird smells or any type of red flag that I found. It's easy to flip and reshape in an instant.

Comfortable to use with firm support
This set of queen-size pillows has a great balance between softness and support. The down alternative fill feels plush and comfortable. The pillows also provide enough firmness to support the neck and shoulders. A better sleep quality achieved with less tossing and turning. For sleeping on side, back, or stomach, the pillows keep their shape and offer consistent comfort. A good choice for the improvement of sleep quality with more comfort.

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.
