Very comfortable pillow
Size: Queen (1 Count), Color: White
I’ve been sleeping with this pillow for a few nights and I really like it. It’s soft but still supportive, and it stays cool during the night. I also like that you can adjust the filling to make it more comfortable. Definitely helped me sleep better.

Fantastic pillow for the price, adjustable is a different ball-game entirely.
Size: Queen (1 Count), Color: White
Overall, I'm quite pleased with this. The fact that it is fully adjustable (adding or removing foam, and they give you a bunch extra) is a massive boon as I like pillows to be pretty low profile. It feels nice to the touch, and compresses nicely but not a ton like down. The memory foam that is inside of it seems to be combined with some kind of a harder material, it's all shredded so I can't tell what it is, but it seems like maybe plastic or something of the kind. Hasn't been an issue in any way, but was just weird feeling it when removing foam. I took a point off because there seems to be some false advertising going on. You can see in their picture that there is a tag that says bamboo side, the other side of that says cooling side. They also mention it in their advertising. As far as I can tell that is not true at all. The cover unzips so that you can remove the material so you can see that there is nothing on either side of it, and both sides appear visually identical to each other. Certainly I would NOT call this a cooling pillow in any way. It's maybe decently cool if you leave it in a cool place for a while, but over the course of the night warms up quite a bit. I did not notice any appreciable difference in the cooling of either side of it. There is a definite noticeable smell to it, but I wouldn't call it 'bad' like most memory foam things are when they come from the factory. It smells kind of like some kind of cleaning solution in a noticeable but not unpleasant sense. All in all, for the price this is a fantastic pillow and I would definitely recommend it.

Most Comfy Pillow Ever Used
Size: King Size Pack of 2, Color: White
I recently purchased the BETU Cooling King Size Pillows Set of 2, and I have been thoroughly impressed with their quality and performance. These pillows have truly transformed my sleeping experience, making them an essential addition to my bedroom. First and foremost, the shredded memory foam provides fantastic support while remaining incredibly comfortable. These pillows adapt perfectly to my head and neck, offering excellent support for back, neck pain relief, and side sleeping. The adjustability of the memory foam allows me to customize the firmness to my liking, ensuring a perfect balance between soft and firm support. This customization has made a tremendous difference in my sleep quality, reducing any discomfort and ensuring I wake up feeling refreshed and pain-free. One of the standout features of these pillows is their cooling capability. As a hot sleeper, I struggled to find pillows that keep me cool throughout the night. The BETU Cooling Pillows effectively dissipate heat and maintain a comfortable temperature, allowing me to enjoy a restful and uninterrupted sleep. The cooling technology is truly a game-changer for anyone who tends to overheat during the night. The pillow covers are another bonus. They are soft, breathable, and easily removable for washing, ensuring that the pillows remain fresh and hygienic. The white cover adds a clean and elegant look to the bedding, making them aesthetically pleasing as well. The king size is generous and luxurious, providing ample space and comfort. Whether used for sleeping, lounging, or reading in bed, these pillows offer an unparalleled level of comfort and support. In summary, the BETU Cooling King Size Pillows Set of 2 is an exceptional product. The combination of shredded memory foam, adjustable firmness, and cooling technology makes these pillows perfect for hot sleepers and those in need of superior support for back and neck pain. The high-quality covers and overall design further enhance their value. I highly recommend these pillows to anyone looking to improve their sleep quality and comfort.

Cool, Supportive, and Great for Hot Sleepers
Size: Queen Size Pack of 2, Color: White
These cooling pillows have been a great upgrade for my sleep. The shredded memory foam provides nice support while still feeling soft and adjustable. I like that the pillows keep their shape and don’t go flat during the night. The cooling fabric really helps if you tend to sleep warm. They feel breathable and comfortable, especially compared to traditional memory foam pillows that trap heat. The queen size is generous and works well for both side and back sleeping. Overall, a great value for a set of two pillows. Comfortable, supportive, and noticeably cooler than my old ones. I would definitely buy them again.
