Great Quality
Size: King (Pack of 2)
Great quality and definitely worth the money. The cooling effect actually works with the pillow. Extremely comfortable, not too squishy and not too firm. To me, it feels very supportive.

Very comfortable, luxurious, and affordable.
Size: Queen (Pack of 2)
Great pillow. Feels soft enough for comfort while being cool and cozy. There could be more filling to make it slightly more firm but otherwise a great pillow.

Memory Foam Pillows
Size: Queen (Pack of 2)
recently purchased the OSBED Cooling Adjustable Shredded Memory Foam Pillow, and it has made a noticeable difference in my sleep quality. One of my favorite features is the adjustable fill, which allowed me to customize the height and firmness to perfectly support my neck and shoulders. Whether you’re a side, back, or stomach sleeper, it’s easy to find a comfortable setup. The cooling cover does a great job of preventing heat buildup throughout the night, which is a huge plus for anyone who tends to sleep warm. The shredded memory foam provides excellent support while still feeling soft and comfortable, and it doesn’t flatten out like some traditional pillows.
