Soft but Supportive, Sleeps Cool！
Size: Queen (Pack of 2)
Very comfortable and adjustable pillows. Good neck support for side and back sleeping. They feel cool and not too hot at night. Great value for a set of two. Happy with my purchase.

LOVE IT but cooling depends on readjusting frequently
Size: Queen (Pack of 2)
I’ve actually been pretty happy with this product overall, especially for comfort and the initial cooling effect. When you first sit or lay on it, it definitely feels cool and refreshing, which is a huge relief if you run warm or live somewhere hot. Humanity continues its decades-long campaign against functional air circulation, so products like this are doing important work.
That said, I do think it’s important to be realistic about expectations. The cooling effect doesn’t stay perfectly consistent in one spot forever. After sitting or laying in the same position for a while, the area naturally warms up and you’ll usually need to shift or readjust to feel the cooler sections again. It’s not “ice cold all the time” magic despite what some listings might make people imagine.
Even with that limitation, I still think it works well and is worth purchasing. The materials feel comfortable, the quality seems solid, and it absolutely helps reduce heat buildup compared to regular fabric or cushions. I’ve found myself using it regularly, especially during warmer days and nights.
So if you go into it understanding that movement/readjustment is part of how the cooling effect works, it’s actually a very good product and noticeably more comfortable than standard alternatives.

Large and thin
Size: Queen (Pack of 2)
This pillow is large and relatively thin, and it's not soft to the touch; it has a granular texture inside, which I prefer. However, it's too high and too soft for me.
