These pillows are amazing. I absolutely love them. I’m going through menopause, so I’m constantly hot, then cold, then hot again. These pillows are truly cooling, and they make a huge difference. I’m a side sleeper, and they are incredibly comfortable. They’re worth every penny, and I highly recommend them to everyone.

Not all the same! Some Great, some not.

I bought the queen 2 pillow green blue pillows first. Absolutely love them. Later I saw they had them with cooling on both sides and bought the queen 2 pillow set of that..not the one that said firm. These new ones are way over stuffed and very firm, they do not sink in softly like the first ones. So I would only get the green/blue tag ones they are 5 star-best i have used, this last one 3 star and regretting them. I took enough stuffing out of the two new ones to make 1.5 new pillows, now descent but not the soft comfort as the first, I thought that was what I was paying for. So it's a gamble. The lighter color stuffing is soft and has more of a memory foam reaction, the other darker one feels like stiffer foam with more air in it. It's still soft but doesn't feel like memory foam.
