Average pillow that might be great for some folks, not for me
Color: White, Size: Queen (Pack of 2)
I should have know this would be like every other pillow I've ever ordered. It's too puffy for me. No give. It claims to offer better support for side sleepers but instead it's giving me kinks in my neck. Not for me. Not adjustable. Not versatile. Standard materials. White. Can't speak to washability and durability as I have had it long and haven't washed it.
fair price for two standard pillows.
I really wish all these bedding companies would stop rolling and vacuum sealing pillows and such.

Just perfect. Well made, No Issues Just one perfect sleep zzzzzzzzzzz😴
Color: White, Size: Queen (Pack of 2)
I had down pillows, and foam pillows, and other synthetic pillows etc and some were ok and others were not. I cannot get a great nights sleep if I am constantly having to adjust my pillow during the night. I ordered these pillows as I sleep on my side mostly but sometimes on my back. When they arrived I followed the directions (as they are in a vacuum pack) and only takes a few minutes for them to acclimate. Then put pillow cases on them and off to bed. I had the BEST sleep I have had in YEARS !!!!! The pillows are great. They keep your head comfortable and cool (No Sweating) and super comfortable. The only issue is after a perfect nights sleep, I find I really do not want to get out of bed in the morning..One great thing, is I am retired so I really do not have to get up out of bed until I want to 😴😳. The pillows are well made and feel like expensive down filled pillows but softer. I am VERY satisfied with the pillows. I just wish I would have found these pillows years ago. But now I have them and the perfect sleep that they provide. Dr Dave

Great sleep
Color: White, Size: Queen (Pack of 2), Color: White, Size: Queen (Pack of 2)
Finally found a pillow that is comfortable. Tested about 5 until I found the right one. This is perfect for back and side sleepers. Firm, but soft. Just enough filling and great quality. Will hold up for many years.

Good overall
Color: White, Size: Standard (Pack of 2)
Bought these for our guest bedroom. They are quite overstuffed, so if you like full pillows this will be your thing. As such they are dense and firm. The height is a bit much if you are small framed, but are comfortable overall and stay cool enough to be nice in the summer.
