Pretty decent for the price. Along with its conventional use, those pillows are pretty comfy to sit on. Pillows are for more than just sleeping; they’re excellent seat cushions!

A true medium firm pillow
Size: Queen - Pack of 2, Style: Soft, Configuration: Pillow
I like a medium pillow that lets my head sink in a little bit so my neck isn't cranked at an angle but not to the point where it sinks in completely. You can also scrunch it a little bit. Also love that it's queen size, as most queen sheet sets for come with queen pillow cases, not standard. I am surprised it worked out, very happy with it.

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
