Not really a "cooling" pillow, but better than a standard or or fiber filled pillow. All these types of pillows and other bed linens are initially cool to the touch, but they quickly heat up to match your body temperature. Although the technology currently does not exist to maintain constant cooling, pillows like this are a good compromise for now. It's nice and soft and is a good value for the price.

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.

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.
