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.

The best thing is coming with a pillow cover to protect the pillow!

Size: Queen (Pack of 2), Size: Queen (Pack of 2)

The item was out of my think. It was soft and in a right deep for me. if you like sleeping on a softy and not high pillow, this is good choice for you!
