Doesn’t stay cool long
Set name: UltraCool Pillow, Standard - Soft/Medium Firmness, Item length width: 30.0 Inches
The pillow was a little softer than I expected. It’s cool at first but at least for me heats up fast.

too soft, useless. but cool, kindah
Set name: UltraCool Pillow, Standard - Medium/Firm Firmness, Item length width: 30.0 Inches
the problem with these "cooling" pillows is any cooling effect is almost completely negated by a pillow case. this particular pillow is cool to the touch, but completely useless as it flattens out completely, way too soft I think for anyone. I would not recommend this "NASA" pillow for anyone for anything. Maybe for 10 bucks, but certainly not what they ask for this. I did keep it though. It is "cool" but only for a moment and your flipping it around like any other pillow. also way too soft. BUt, it has been cool enough to get me back to sleep.

Fantastic pillows
Set name: UltraCool Pillow 2-Pack, King - Medium/Firm, Item length width: 40.0 Inches
I cannot say enough how happy I am with these pillows. Truly amazing. I put REST pillowcases on them and they are constantly cool/cold.

Love it
Set name: UltraCool Pillow, King - Soft/Medium Firmness, Item length width: 40.0 Inches
I really like this pillow!! It’s a nice medium fluff. I do think it feels cooler. And, when you flip to the “cool side of the pillow” it’s realllly chilly. It’s very long - it sticks out of my king size pillowcase a little bit - but not enough to be bothered by it.
