Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

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
