Flat
Color: White, Size: Queen (Pack of 2)
They are long pillows but definitely flat, I tried and tried to fluff them up and they are about like the $3 Walmart pillows. I will be returning these

Holy Wow!
Color: White, Size: Queen (Pack of 2)
These pillows are so fluffy and material is really soft. They came vacuumed packed. I thought well this will be a return for sure. Followed the directions and placed them in my dryer for 15 minutes. Could not believe how big and fluffy they were. My company always ask for the link and I have ordered them for family members and for myself 4 times. Mine I’ve had over a year and have kept their shape and fluffiness. If you like a fluffy pillow…this is the one. They are the best!!!

Comfortable and good quality
Color: White, Size: Queen (Pack of 2)
So comfortable! We stayed at an Airbnb that used these pillows and went home and ordered some! These are similar to another more expensive pillow I’ve used but way better price. The filling feels nice and they don’t go flat or get lumpy so far.

Luxurious, not pokey! Better relaxation and sleep! Worth the price!
Color: Classic White, Size: King (Pack of 2)
I've tried multiple feather pillows, and this is by FAR the most comfortable low-to-mid-priced pillow I've found so far. About the same price as what I've bought at a discount store, but it has good loft and is pokey NOT AT ALL! I'm sensitive to pillow height and stiffness as I have neck/spine damage, but this is more comfortable. This feels luxurious, and I've had more frequent and higher-quality sleep. Will buy again!
