Pillow for everyone
Item Package Quantity: 2, Size: Queen
I think this pillow is too firm. I prefer a softer pillow but wanted to try this one. I may just have to get use to it. I will keep using it and see if I cannot get use to it.

Gonna get more for the guest room while I'm thinking about it.
Item Package Quantity: 4, Size: Queen
I will buy these again in a few years. I got 2 for me, and two for my man. They look super nice and full, and squish perfectly when you lay your head down on them.
They are economical and priced nicely. They fluff decent when you fluff them, and I love my pillows again. These got rid of my headaches from neck trouble.
I love these pillows. I'm gonna actually buy some right now for my guest room while I'm thinking about it. I compare these to that hotel I slept at once that had the most amazing pillows. Clean crisp fresh and soft. But not too soft. They are definitely soft, but cradle your head like a hug.

Well made and soft Resilient but not memory foam Good for back or tummy sleeper
Item Package Quantity: 4, Size: Queen
These pillows are well made I put them in the dryer on medium heat for 10 min 2 at a time, and they doubled in fluffiness They're soft to the touch as well as in plushness/depth They are resilient but not memory foam I don't think they would be firm enough for a side sleeper but nice for resting on your back or tummy

Comfortable!
Size: King, Unit Count: 2.0
After vacationing, I wanted to buy the brand of pillows used at the resort where we stayed because they were so comfortable. I landed on these pillows instead because of the reasonable price point. These pillows are every bit as comfortable. They are fluffy and supportive without being too heavy and stay cool. These pillows are comfortable and well made. They support both my head and neck and e long enough to use as a body pillow for side sleeping. I would recommend these pillows!
