Soft yet supportive
Size: Queen
I have been through 4 other pillows in the last year trying to find one that supports but isn't too firm. I gave this one a shot and am really loving it. It's soft, comfortable, supports without hurting my neck or shoulder. I am short so some pillows are too high for me. I'm mainly a siide sleeper, this pillow is great as I can place my head anywhere not just middle of very end like the other pillows I was trying. I can sink into it a little yet still have support and it doesn't crush down. It comes with more filler but haven't needed it. I put it in the dryer on ultra delicate when I first got it and it fluffed nicely. Very happy with this product as I am now getting more sleep.

Absolutely in love with this pillow!
Size: King, Size: King
I’m so excited about this purchase — this pillow turned out to be amazing! I’m a side sleeper most of the time, and the way the edges are designed makes it incredibly comfortable and supportive. What really surprised me is that even when I slept on my back (which I normally don’t like), I felt super comfortable. I actually woke up still lying on my back — and that never happens! I know it’s healthier to sleep that way, so I’m really happy about that and hope it becomes a new habit. Before this, I tried a few regular memory foam pillows, but they always felt too firm and my neck would get tired. This one, with the shredded memory foam, is so soft and cozy — it molds perfectly without feeling lumpy. The King size is perfect too — my little Pomeranian loves to rest his tiny head next to mine on the pillow. I don’t know why he does that, but it’s adorable. And I have to mention the packaging — the box was so high-quality and beautifully made that I just couldn’t throw it away. I’m definitely keeping it to store something in. Overall, I’m super happy with this pillow and will be ordering a second one soon. I only got one to test it out, but now I’m totally convinced. Thank you for such an awesome product!

This is Truly the Best Pillow!
Size: Queen
This is the side sleeper version of the best pillow out there. My 26 year old son was always complaining about his pillow and his neck and back hurting. About every year I’d buy him the next “best” pillow promising to be the best but they never worked for him. I read an article saying THIS pillow was the “Goldilocks” of pillows. So since he sleeps in all positions, I got him the regular shaped pillow. The next morning after his first night with the pillow, he came out of his room talking about how wonderful his pillow is. Same thing the next morning. And the next. And the next. Then I thought to myself, my current pillow is the best I’ve had but I’m not in love with it. But I’m a side sleeper so I purchased this particular contoured pillow for me. NOW I UNDERSTOOD WHAT MY SON WAS TALKING ABOUT. I became the person who went on and on about my pillow. Until my husband told me to replace his with one of these side sleeping versions for himself. And he loves it. Then we got a regular pillow (for those who sleep in all positions, but this same company) for our guests. My best friend came to visit, immediately noticed the pillow upgrade from previous visits and when she returned home, she purchased one for herself. This pillow is like a feather pillow except it is filled with tiny squares of memory foam. And it comes with an extra pack of stuffing, so you can add or remove stuffing to customize it perfectly for you. None of us in the house added filling, and my son removed some that came with his pillow. I also sleep with a body pillow and have for years. And I was wishing this came in a body pillow version until I realized I could make my own. I bought a zippered body pillow case. The larger size. I think it was 54 inches long. And I bought a king size pillow and used the extra stuffing pack that came with that pillow along with the 4 packs that came with the other pillows that we didn’t use. Though you could probably do the same thing with two standard size pillows. These pillows are on the expensive side but they go on sale during every holiday. That’s when I purchase them. Oh and my body pillow is HEAVEN. Between that and the pillow, I spend my nights in fluffy cloud goodness.
