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.

Comfortable and stays cool

Color: White-cooling Basic, Size: Queen(Pack of 1)

Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

Comfortable and Supportive, but Adjust the Filling

Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)

I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.
