Great pillow, but the cooling effect depends on the cover
Color: Blue-ice Plus, Size: King(Pack of 2)
I really like this pillow overall. It’s comfortable, supportive, and feels well made. When you use it without a pillowcase, it definitely feels cool to the touch and does what it claims in terms of that initial cooling sensation.
However, once you put a pillowcase on it, you can’t really feel the cooling effect anymore. I’ve tried multiple different pillowcases made from different materials, and none of them really let that cool feeling come through.
That said, I still love the pillow itself. It’s comfortable and supportive enough that I’m keeping it. Just keep in mind that the cooling feature works best without a cover, which isn’t ideal for everyone.
Overall, a good pillow — just manage expectations about the cooling effect once it’s covered.

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.
