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.

These pillows perform wonderfully and they hold up!
Color: Grey, Size: Standard, Color: Grey, Size: Standard
I have had these pillows for 5 years, so mine is not in brand new condition in this photo but they still appear pretty good and function wonderfully. I recommend these to others looking for a soft but supportive pillow. They are the standard microfiber cooling ones. I have one and my daughter (7) has the other. We use them every night and they are just the perfect amount of medium-softness for both of us despite us being very different in size! Still fluff back up, have just enough support and height or thickness in my opinion (I don’t like very firm microfiber pillows as much, and I don’t like the feather pillows that aren’t goose down because they get crunchy and flat). Love these pillows, the price is super reasonable for the product they provide. They have held up this long, I’d say they are of good quality. I’ve just ordered another set for a visit to my mothers house! Our favorite pillows!
