Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep
