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

Okay pillows

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.
