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.

Does not cool, is hot actually

I am very disappointed with this product. I write a lot of reviews and give credit where credit is due. I wish credit was due here. I bought this as a gift for my wife. She slept on it for a few nights and finally stated that it never cools and is hot instead. And so I tried it and found the same thing. I bought an inexpensive cooling pillow from Costco and we both found that one to cool a little bit and it isn’t hot. I’m summary, you don’t always get what you pay for and at $100, this pillow does not deliver. It’s supportive and it seems well made, which is why I give it two stars. But it does not deliver any cooling. Save your money and try a different pillow.

Does what it claims, supportive and eliminates heat.

Size: King (Pack of 1), Style: Single Pack

Its a bit pricey however when it comes to sleep quality im glad to pay for name brand. No tossing or turning to escape to the cold side of the pillow. Feels firm which was concerning at first however once you settle in its very comfortable. Seems to be just how foam pillows are made. Happy with the purchase.

I have found the PERFECT pillow for me!!!

Size: King (Pack of 1), Style: Single Pack

I just absolutely never write a review on anything, but I have to praise this pillow from the rooftops! I have not slept this comfortably is so many years! I have plushness and support, my neck is in alignment, and when I turn to sleep on my side the pillow doesn’t block my airflow. This pillow is perfectly made for me!!!!
