Best Pillow I’ve bought in a while
Fill Material: Down Alternative, Size: King Size
Very comfy pillow. Holds up better than the last 7 I bought which went flat after a week. It also comes with extra fill which I have not had to use yet but overall very happy!

Cozy & Comfortable
Fill Material: Down Alternative, Size: Queen/Standard Size
This pillow was a big surprise! Despite the size, it is so soft & comfortable. Being able to add & subtracting filling is wonderful. It's like having a custom pillow just for me. I am a stomach sleeper. I am able to cuddle the pillow & be very comfortable. Plus it recovers it's shape.

Overall a great pillow
Fill Material: Down Alternative, Size: King Size, Fill Material: Down Alternative, Size: King Size
I slept on it last night and I do think I’ll like it. I was used to a memory foam pillow, son this will be a change. My reason for 4 stars is because the zipper barely opens and my husband and I tried everything short of ruining the pillow. In the end I had to stuff extra stuffing into a pretty small hole. Nothing seems wrong with the zipper but I saw another review said they couldn’t add more filling. If they fix that issue then I’d rate it 5. Yes it is soft but it doesn’t go flat and if you adjust and add some more under your head it doesn’t shift. I do recommend if you like a plush pillow.

excellent medium consistency pillow
Fill Material: Down Alternative, Size: Queen/Standard Size
Pillow is medium firmness with extremely uniform compression consistency. i have a very particular desire for something not too hard or too soft and this is the sweet spot... more stuffing is provided so you can add (or remove) some if needed to get what you like...i didnt need to but liked to have that option. also the feel of the cover is nice.
