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!

Best pillows ever
Size: King (Pack of 2)
“These pillows are incredibly comfortable! They’re soft, supportive, and hold their shape really well. The material feels high quality and makes relaxing or sleeping so much more enjoyable. I noticed a difference right away — whether I’m watching TV, reading, or going to bed, they provide the perfect amount of comfort. Definitely one of the best pillow purchases I’ve made!”
