Great little pillow
Color: White & Light Blue, Size: S - 16 x 12 Inch
Works perfectly since stuffing can be removed to make it just the right thickness needed for you. Soft & cool to put your head on plus very well made with quality materials.

Great adjustable travel and sleep memory foam pillow
Color: White & Light Blue, Size: M - 18 x 13 Inch
Perfect travel pillow. You can change how “fluffy” the pillow is by opening the zipper and removing some of the memory foam. Once I did this, it was the perfect supportive pillow to sleep on at night when I travel. I am a side sleeper and this pillow worked really well. It has one side that has cooling material and one side that has regular material. I followed the instructions to let the pillow air out for 24 hours and never noticed a smell.

BUY THIS PILLOW!!!
Color: White & Light Blue, Size: L - 23 x 16 Inch, Color: White & Light Blue, Size: L - 23 x 16 Inch
I originally purchased the small Cooling Adjustable Memory Foam Pillow because I had shoulder surgery coming up and wanted something that might help me sleep more comfortably. What surprised me was how much I loved it before I even had surgery. After trying it, my girlfriend used it for just a few minutes and immediately wanted one of her own. I ordered her the full-size version, and she loves it just as much as I do. After my surgery, I realized I wanted the larger size too, so I ordered another one for myself. The best way I can describe this pillow is that it somehow adjusts perfectly to whatever position or pressure you put on it. It always seems to provide just the right amount of support and comfort. I honestly don't know how it does it, but it works incredibly well. I've purchased a lot of products over the years, and I rarely take the time to write reviews. I only do so when something truly exceeds my expectations, and this pillow absolutely does. The comfort, support, and value for the price are outstanding. My only suggestion to the company is to expand the product line. I'd love to see additional pillow styles, shapes, and specialty versions because based on my experience, I would definitely purchase more in the future. Thank you for making such a fantastic product. This pillow has made a noticeable difference in both comfort and sleep quality for both of us. Highly recommended!

Nice pillow
Color: White & Light Blue, Size: M - 18 x 13 Inch
Nice pillow. It's cooler on one side, but when you put a pillow case over it, of course that takes away the cooling effect. I like the size, weight and support of the pillow. Not too stiff or too soft. Hope it lasts a while. Haven't tried washing it yet.

Best cooling pillow!
Color: White & Light Blue, Size: S - 16 x 12 Inch
Wow! I’m so impressed! This is the best little cooling pillow! I use it on a daily basis, I only wish I had found it sooner! I suffer from night sweats and this pillow has been a big game changer! Perfect amount of firmness and comfort and not overly thick, just perfect! Wonderful value for the money! No odor!
