Perfect pillow
Size: Queen Size(2 Pack)
It’s a beautiful soft Material, way better than any pillow I’ve ever owned. It’s cool to the touch and remains fluffy and durable. I’ve had it over a month and still love it just as much as day one! The neck support is also very much appreciated! The size is perfect for my pillow cases. All in all a durable, soft Material, comfort pillow! Will buy again!

Soft, feel cool, Arrived vacuumed package. Put in dryer on cool for 3 Minutes, Fluffed right up!!!
Size: Queen Size(2 Pack)
These pillows arrive air tight, once you open the expand very slowly. I put them in the dryer on cool for about 3 or 4 minutes and they fluffed right up!!! They arrived yesterday evening, I have not used them yet, I will need to remove some of the shredded Memory Foam as it is way to much for me. I will update after a night or two. they are soft to touch and feel cooler if you leave your hand on a for little bit. I'm excited to try them out. Hoping and praying they work for bad necks, backs and shoulders, seems to be Nice quality.

Really supportive, comfortable pillows, great value.
Size: Queen Size(2 Pack)
When I received these pillows, I followed the directions to fluff them. They were delivered vacuum packed. The first night I slept on them, I didn’t remove any of the filling. That was a problem because the pillows are so over stuffed that it was difficult to sleep on them. I was disappointed until I removed about 1/3 of the filling. Doing so made all of the difference. These pillows are very nice. They keep their shape during the night and provide excellent support for my neck and head. They don’t flatten out or separate like regular shredded foam pillows.
They are well made with an outer cooling cover as well as a inner zippered cover for the foam.
I love the fact that these pillows are adjustable. I saved the foam I removed in the zippered bag the pillows arrived in, in case I needed to restore the foam in the future. They are a very good value for the money.
