Very nice pillow
Color: Cut-out White, Size: King
I was skeptical of spending this much money on a pillow, but so far I'm glad I did.
It's very comfortable, and the shape does seem to help. I injured my neck/shoulder years ago, and I would wake up 1-2x per week heading slept wrong making my neck and shoulder stiff and painful in the morning. This pillow has so far prevented that.
This pillow has also significantly reduced my snoring, according to both my Samsung watch and my wife.
I'm a side sleeper.
This pillow can be as firm or soft as you want since you can add or remove filling. It comes with a bag of extra filling just for that.
I wouldn't say its cooling, but it certainly isnt too warm either. And I'm someone who sleeps hot.
All in all, I'd buy it again.

this is it (hopefully), no chemical odor
Color: Original White, Size: Queen
Over the years, I have spent a lot of time and money buying pillows. I can never seem to find one that fits my needs. I thought this would be a good option to try because this came up as a top rated pillow from consumer reports.
I really think this pillow might be the last pillow I ever need. I saw all the good reviews and I also read all the bad reviews. Pillows are very personal, and a pillow that works for one person may not work for the other person but, I decided to give this a try.
I was so excited. This was on sale at Amazon and I got it same day. I have a lot of neck issues and pinched nerves so I thought this pillow would help. Once I took it out of the box, I fluffed it up by hand because I don’t have a dryer. Within 15 minutes the pillow was really fluffy. I tested it out. I’m a side sleeper. It didn’t work too well. I removed some of the stuffing which is luxuriously soft. And it seemed to be comfortable. This morning I woke up with a horrible neck and headache. So, I took a little more stuffing out. It seems to feel better now. This gives just the right amount of support. It doesn’t give too much pushback and it also doesn’t go flat. Yes, this will flatten out a little bit when you lay your head on it, but not completely to the mattress flat. I fluff it up before I go to bed and it works great. I think I have it at just the right thickness but we will see how it goes. Surprisingly, it was not too hot for me like others have reported. I do have a temperature control system on the bed so maybe that’s why the pillow temperature didn’t bother me as much. I did not have any pain in my ears from sleeping on a hard pillow. That was a big plus. It gives Justin enough support and not too much pressure so it’s perfect. The outer shell is really nice. The shell and zippers seem to be good quality. I still use a genuine silk pillowcase because I like it. I think this is my forever pillow. I will add an update after I use it for a while if anything changes. I am hoping for good durability. Last thing, this also comes with extra stuffing if you like your pillow, extra high, or if your pillow starts to go flat, you have more stuffing to put in it. Putting your pillow out in the sun or in the dryer once every couple of months will help to keep it fluffy. I don’t think I would ever wash the foam on the inside. There’s no reason for that. The outer shell is what’s going to get most dirty.
Just know, I liked it so much I bought another one immediately.

Rediscoving the Great Qualities of this Pillow (after Originally Rejecting It)
Color: Original White, Size: Queen
I recently 'rediscovered' this pillow... having purchased it a year or so ago, when neck + shoulder issues prevented me from being very happy with *ANY* pillow! Believe me, I tried so many! Back then, after repeatedly adjusting the fill of this COOP queen-size pillow, I ultimately stashed the whole thing in a closet. But now, it has unexpectedly re-entered my life... and I'm finally liking it.
It helps that I've resolved most of the neck + shoulder issues (thanks to a year of PT). Plus. I realized that I had removed way too much fill... leaving about as much support as a pile of gently scrambled eggs. So, now that I'm in much better condition and have added back a lot of fill, I'm finding this pillow quite satisfying... yes, actually good! These days, I wake up each morning with a much happier neck.
I do not. however, use the thick, quilted, zippered outer cover that came with it... as I find that stiffens + firms up the pillow a little too much for my taste. So, on top of the thinner, stretchy, zippered inner cover (also provided with the pillow, to contain the fill,) I've replaced the quilted outer cover with a jersey-stretch, zippered, cotton pillow protector. which is lighter weight and more malleable.
As a person who has been traveling for years—by necessity—with a personal pillow from home, I'm now recognizing the extra advantages of this COOP pillow: For travel, its parts all compress well + easily (while for sleeping, the fill is light + lofty, but also supportive, as long as you don't remove way too much). And the pillow's components all readily come apart, so they can be packed separately...even the stuffing can be separated into smaller zip-lock packets, if needed—meaning there's never a need to squish an entire, impossibly big, somewhat dense pillow into a suitcase (or even a compression sack). Quick + easy to disassemble and reassemble. Really, the COOP can be treated as a build-your-own pillow (remember, I changed out the zippered outer cover and adjusted the stuffing volume to my own prefences). It's not cheap, but these days, remarkably, it's doing the trick for me. So glad I didn't get rid of it.

Great pillow and company
Color: Crescent White, Size: King
I have a couple of Coop Home pillows and loved them. They are several years old and I was on the search for a replacement. I tried 2 other brands, one cost more and the other cost less. Returned 1 and used the other for a short time before I had to go back to my old Coop pillow. I started looking at crescent pillows and did some research. This type of pillow is great for side and back sleepers. Being a side sleeper I looked into the best rated. Coop Home crescent pillow was not rated #1 but it was close. The top rated pillow cost 2.5 times more and I could not justify paying that. I am happy to report that I am waking up less (before every 1.5-2 hours). It comes with extra fill and I love a very firm pillow so I emailed customer service to see if I could get more filling. This was on the weekend and in 1 day they responded that they would be happy to. Now that is great customer service. I sleep warm and have no problem with a hot head. It comes with a cover but I use silk pillowcases and it works fine. I will say when I first got the pillow it was very thin and flimsy. I had some doubts but followed directions and put in the dryer on low. Came out perfect. Highly recommend this pillow and company.

Best pillow I've ever owned
Color: Cut-out White, Size: Queen
While the pillow looks anemic when it first comes out of its packaging, it puffs/firms up beautifully after time in the dryer. I haven't had any odor issues.
I'm mostly a side sleeper and at first I thought there wasn't enough of the extra fill, so I put it all in. I've ended up needing to take at least half back out to keep my head at the correct angle.
While this can fit in a standard pillow case, it just barely fits and keeps coming out - at least at my fill level. Queen pillow cases are much better.
This is so much more comfortable than any of my previous pillows. I don't need to stack multiple pillows to get the right support. I'm no longer waking up with neck or shoulder or arm pain. I'm recommending it to pretty much everyone and I've purchased a second pillow to keep at my parents for when I visit!
