excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to.
1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then.
They both needed a firm pillow that is not super soft, firm but not achy.
Finally found the perfect one.

This Pillow Is A Must Buy!! What Are You Waiting For?
Size: Queen (Pack of 1)
This is, without a doubt, the best pillow I have ever owned. One of my favorite features is the adjustable shredded memory foam fill, which allows you to customize the loft and firmness by adding or removing foam to suit your sleeping preferences. As both a side and back sleeper, I found it incredibly comfortable and supportive.
The overall quality is excellent, from the materials used in the pillow itself to the thoughtful packaging. The removable cover is washable, although I personally use a pillowcase to keep it protected. I also appreciated that extra foam is included, making it easy to fine-tune the pillow over time.
The difference in my sleep quality was noticeable from the very first night. I’ve been sleeping more comfortably and waking up feeling more rested ever since I started using it. Considering the quality, comfort, and customization options, I believe the $75 price point is well worth it. I am so impressed with this pillow that I plan to purchase another one in the future.

This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability
Size: Queen (Pack of 1), Size: Queen (Pack of 1)
I purchased the DreamyBlue Signature Adjustable Pillow for my husband because he often experiences back discomfort, and many of the pillows we had previously would become flat and lose their support over time.
This pillow has exceeded our expectations. It is incredibly soft, comfortable, and comes with extra filling, which allows you to adjust the firmness to your personal preference. We really appreciated having that option.
Even after extended use, the pillow has maintained its shape much better than other pillows we've owned. It provides a plush, cozy feel while still offering good support. My husband finds it very comfortable, and it has quickly become his favorite pillow.
This is a high-quality, well-designed pillow that combines softness, comfort, and adjustability. I would definitely recommend it.

Finally Found a Pillow Worth Keeping
Size: Queen (Pack of 1)
I genuinely feel like I’ve tried every pillow on the market. At one point, I thought Amazon was going to flag my account because I bought and returned so many pillows trying to find the right one.
This is the only pillow that made the cut.
The shredded memory foam filling makes a huge difference because the pillow is both soft and supportive, while still being adjustable to fit the way you sleep. It arrives extremely full and plush, and it even comes with an extra bag of fill, which honestly surprised me. I ended up removing about half of the filling to get it exactly how I wanted it.
I’m a side/stomach sleeper, which can make finding a good pillow difficult since most are either too thick or too flat. This one was perfect because I could shape it exactly how I sleep.
It stays cool throughout the night, has a slightly heavier premium feel, and feels much higher quality than most pillows I’ve tried. Super comfortable, supportive, and customizable.
I would absolutely recommend it and would definitely buy it again
