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.

Not great
I bought these pillows based on customer reviews. I got them and let them poof out after opening... But they are awful. They're soft but there's nothing to them. Very flat and not supportive. I'm literally buying different pillows tomorrow.
