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.

A product that will make a difference!

Color: White, Size: King (Pack of 2)

These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.
