I highly recommend this pillow, it’s great for someone with neck or back problems.
Size: Queen (Pack of 1), Size: Queen (Pack of 1)
I absolutely love this pillow! When it says it’s adjustable it definitely means that. When you first get it, it’s hard to believe that it’s going to be anything but put it in the dryer for a few minutes and it becomes so large. You will definitely have to remove some of the stuffing unless you like a really large fluffy pillow. The stuffing is high-quality and once it has been put into the dryer it becomes a fibrous type material that can be fluffed over and over and go back to the same size. It seems to be a high-quality cover on the outer portion and is thick and has a slight cooling affect. It has a separate cover on the inner portion covering the foam stuffing. I ordered this because I have neck problems and it has been super comfortable for me because I’m able to adjust it multiple times depending on my needs for the particular night when I lay down. Having the extra stuffing means that if the pillow does happen to go flat I can always add the extra that I took out when I received it. It did have a slight odor when it first came, but after putting it in the dryer, it went away immediately. I do think that’s only due to the plastic that it’s shipped in not anything with the pillow. I think this pillow is well worth it price and I would highly recommend it for anyone that is a side or back sleeper or has any type of neck problems.

Amazing!
Size: King (Pack of 1)
Such a great pillow I’m buying another one! You can add or subtract stuffing to your liking. It’s really nice quality, quilted and soft. Best pillow ever. Super comfy and great sleep. Pretty firm with all the stuffing. Perfect the way it came with stuffing on the side. My husband loves it and now I want one.

Totally worth the money
Size: King (Pack of 1), Size: King (Pack of 1)
Right off the bat, the packaging is absolutely adorable and felt like I was buying a premium product. I love that this pillow is adjustable and as a side sleeper, I needed a pillow that is both firm and supportive of my neck. This hits all the boxes. We will be buying more of these for our bed!

Deserves more Stars
Size: Queen
I was very hesitant to make a pillow purchase off Amazon. Turns out it’s the very best purchase! I had chronic neck issues the chiropractor couldn’t resolve. It was the first time, I had an unsolvable issue. I finally decided to spend the money and buy new pillows. My neck issue was 95% resolved the next morning. I’m not kidding! It’s now 100% resolved after a very short period of time. They are a wonderful gift to myself.! quality is top-notch. The support is fantastic. They adjustability is phenomenal and you can adjust the firmness because they give you extra foam. They’re completely worth every penny. I’m 61 years old, 100 pounds and very active. Waking up with neck strain was horrible.

I Hit It With the Dryer and It Became a Real Pillow!
Size: Queen
This DreamyBlue Moon Pillow made a much better first impression than I expected. Out of the package it looked like it needed a pep talk, so I threw it in the dryer to fluff it up and it came back with purpose. Just full on BAM. Pillow achieved. The shape is one of the best parts. It actually feels like a pillow that wants to do its job right. Not too weird, not awkwardly bulky, not one of those ones that looks promising until you lay down and realize your head is now parked on a bag of chopped foam and bad decisions. I also really liked being able to customize it. That part matters more than people think. Pillows are weirdly personal, and most of them give you exactly one option: deal with it. This one lets you adjust the fill until it actually feels right, which is a whole lot better than waking up annoyed and pretending it is fine. And for anyone wondering, mine did not have any weird smell. No chemical funk. No “maybe this needs to live on the porch for a day” situation. It just fluffed up, felt good, and got to work. Overall, this has been a solid win. Comfortable shape, easy to adjust, and none of the usual nonsense. Which, for a pillow, is honestly a strong performance.
