Great quality pillows. Very difficult wrapping.
Color: White, Size: King (Pack of 2)
The Pillows are the real deal. Very fluffy but with good support. I was surprised by the weight of the box they came in, pretty heavy so you know there’s good quality pillows inside.
The one negative is that the pillows are packed in very very tight plastic because they come compressed. But the thing is, it’s really a chore to open them. You have to be careful not to cut through the plastic to the material, but the plastic is put on so incredibly tight that it’s even hard to get your finger underneath.
But I found a way to open them. Near the top, insert A very flat metal ruler as far in as you could get it. Then cut through the plastic that’s above the metal ruler. That prevents a sharp tool from damaging the pillows. As you get through the plastic above the ruler, keep pushing the ruler further down into the package. Believe me, this simplifies what could be a very difficult unpacking. I am very surprised that the company that makes them does not insert the type of opener that you find on boxes you receive in the mail or even packages that you get from the grocery store where you just pull a tab and that opens the package.
These are really good pillows, but you must be very careful about using a sharp object when opening the box and when trying to cut through the plastic. I am a strong man and have the tools needed, a very flat metal ruler, and a box cutter, knife, or razor. Good luck. !!

These hold up very well
Color: White, Size: Standard (Pack of 2)
I have NO luck with pillows. I’ve been in stores & tried them. They seemed ok there. At home, nope. I’ve been getting headaches & neck aches from lousy pillows. I’ll change one, a few nights relief. It doesn’t help that I’m prone to headaches. After reading about different pillows, I settled on these. The reviews were better than so many different ones I was looking at. Including high priced & brand names. I bought the standard size. When I saw, “Customers Usually Keep This”, I kept my fingers crossed. When I received them, I took one out of the package & put my head on it & thought, oh no! This is too hard! I tried it again. Ok….. I slept on it & haven’t had any pains since. It’s soft but firm enough to keep my head from sinking & messing up my neck. I don’t move. No more flipping my pillow over. My head doesn’t go below my neck anymore! This has been 2 months now, but it hasn’t changed at all. I wake up happy, not complaining. No more pains or headaches. This saved me from losing days with a heating pad or an ice pack. The price was excellent for 2 pillows. I can’t believe a blind buy was the answer! These are incredible. Finally, something worked for me.

Awesome Pillows!
Color: White, Size: King (Pack of 2)
These pillows are super soft! I love them. I bought them when I caught a bad cold and needed to prop myself up. Worked so great! Definitely give these pillows a try. They're very reasonably priced too.

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.
