Comfy, but not Cooling
Comfy for a stomach sleeper, but doesn’t stay cool as promised by other reviews.

Meh. Not impressed but not the worst.
Size: King (Pack of 1), Style: Single Pack, Size: King (Pack of 1), Style: Single Pack
TL;DR: Not worth the money I’ve had quite a few cooling pillows and, while not the worst, this is also not the best in my experience. First, I had to take the cover off. It was ridiculously thick, thereby negating any cooling effect that I could feel. With the cover removed, the cooling sensation is noticeable when laying your head on it and it lasts for a minute or so. On the bright side, when the cooling feeling completely dissipates, the pillow doesn’t feel hot like some others. Having to lay on it without the cover makes it less comfortable because of the encasing material. Other than that, I’d rate the support and comfort as mediocre as well. Not worth the money in my opinion, maybe if it was about 33%-50% less.

Firm yet comfortable
We have purchased several of these pillows over the past few years. They have held up well and held their shape and firmness, even with washing. They are the right height for neck comfort and we do not need to double up pillows anymore to get a good night's sleep. They are also a good firmness to rest against while sitting up in bed.

Is this a Casper or Tempurpedic?
When I went to wash the pillow covering I discovered that it iterally had a Tempurpedic factory pillow covering underneath the Casper factory pillow covering - leading me to believe that it was either a return item shipped out as new, and the previous owner actually returned a Tempurpedic pillow disguised as a Casper, or Casper is actually manufactured by Tempurpedic and uses the Casper brand to upcharge. Either way - it's turned out to be an overly expensive - mediocre pillow.
