Great
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
The medium density support is exactly as advertised and provides more support and firmness. The pillow is taller because of the density so maybe not great for stomach sleepers but works well for back and side sleeping. I bought this because I tried the same pillow at my sister’s house and woke up without neck pain for the first time in forever. Honestly better than my $100 pillow.

These are firm pillows not medium as described.
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
These pillows are much too firm to be medium density as described. They are too stuffed full of filling. They barely give when my head is on them, so my neck ends up twisted. And they are ridiculously heavy. The filling is also uneven. I wish there was a zero stars option. Definitely returning them.

Medium Density is flat and underfilled, soft is better. Get medium if you hate life or for in-laws
Size: King (Pack of 2), Style: Medium, Configuration: Hometextile
I thought the medium density version would be a firmer version of the soft version but I was very wrong. The medium version is very flat and has no support. Medium density feels like a cheapo $2 black friday pillow that's only useful as a decoration. I suppose the medium density fill version does have its use, you can get this pillow for a guest bed. Perfect for the in laws/guests you dislike so they don't get too comfortable and overstay their welcome.
The soft one is very filled and nice to sleep on. The soft one feels firmer than the medium version, probably due to the fact that its probably filled twice as much as the medium density. Would recommend to get the soft density fill version of this pillow.

Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation.
However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through.
That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone.
Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.
