Perfect Balance of Comfort and Support!!
Size: King / 2 Packs, Color: White/Soft
I’ve been using these pillows for a few days now, and they’ve been amazing. They’re soft but still have that medium-firm support that keeps my neck comfortable no matter how I sleep. The 100% cotton cover feels really smooth and breathable, and I love that they’re hypoallergenic.
They fluff up nicely after washing and keep their shape well. Honestly, they feel like hotel-quality pillows at home

Very comfortable
Size: Queen / 2 Packs, Color: White/Soft
These pillows are the best investment I could have possibly made. They are of incredible quality and are soft—qualities that allow you to rest much better, as prioritizing such things is essential for achieving deep sleep.
And with a super soft fabric.

Okay pillows
Size: King / 2 Packs, Color: White/Soft
Soft and comfortable, the only downside to the pillows is that the feathers pop out from the cover and pinch

Do not recommend
Size: Standard / 2 Packs, Color: White/Soft
At an Airbnb in Marine CA, these pillows were on my bed. They were so wonderful, I took a picture of the label so I could order them for myself. After a few weeks, the feathers began working out of casing and would poke my head. I then put them in two pillowcases thinking that would make a difference- nope. When I removed the outer pillowcase to launder, there were 69-80 little feathers between the two layers. I went back to my old pillows and although they aren’t as great as down pillows, I don’t miss being poked and finding little feathers between the pillowcases and in my bedroom. Four months later, I am still finding a few random feathers in my bedroom.
