Love this pillow!
Size: Queen Size: 27.6"L x 15.7"W soft, Color: White
I sleep on my side and this pillow is great! I also enjoy the cooling aspect. I forgot my pillow at a hotel and had another one ordered before I got home.

Life-Changing Comfort – Best Pillow Ever!
Size: Queen Size: 27.6"L x 15.7"W Medium, Color: White
I can’t say enough good things about the Releep Memory Foam Pillow—it’s an absolute game-changer! From the very first night, I noticed a huge improvement in my sleep quality and neck support.
One of the best features is the dual-sided design—a firm side for extra support and a cooling soft side that feels like sleeping on a cloud. I love being able to switch between them depending on how I’m feeling. The memory foam provides just the right balance of support and comfort, cradling my neck perfectly and keeping my spine aligned. No more tossing and turning or waking up with a stiff neck!
The cooling side is a dream! It actually stays cool throughout the night, which is a lifesaver for hot sleepers like me. I used to constantly flip my pillow looking for a cool spot, but not anymore.
If you suffer from neck pain, tension, or just want a better night’s sleep, this pillow is 100% worth it. I’ve tried so many pillows over the years, and nothing comes close to this one. I wake up feeling refreshed, pain-free, and ready to take on the day. Highly, HIGHLY recommend!

Nothing like I hoped
Size: Standard Size: 23.6"L x 15.7"W soft, Color: White
This is a piece of foam in a "cooling" pillowcase, which is not cooling and the foam goes flat. No support and no cooling. Very disappointed that you cannot trust reviews for true product information. The good part is you can return which I did.

Worth the investment
Size: Standard (Pack of 1), Size: Standard (Pack of 1)
I’ve owned several. I toss them about every 5 years because well I haven’t found a way to wash it and not ruin it. I used to buy it at bed bath & beyond before they closed. And it was the same price there. It’s not memory foam. It’s latex. So if you are allergic- buyer beware. But it has a nice little bouncy- ness to it. Which I love. Cradles my head & neck.
It has a zippered cover on it you can remove & wash. This one seems to have a thin, protective permanent cover thing on it. I assume so you potentially can wash the pillow. May attempt that in a few months.
