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!

So nice your wife will steal it for herself
Color: Original White, Size: Queen
This, this is the god of all pillows I’ve ever purchased. It’s the perfect balance of firm and soft and it’s easily adjustable using the added filler. I’m a side sleeper so having a primary pillow is a must. Combined with a decent secondary pillow this one provides a perfect amount of support. This pillow is so nice, my wife ‘borrowed it’.

Favorite pillow!!
Color: Original White, Size: Queen
Absolutely love this pillow! Bought my husband one a year ago after he was waking up with neck pain. Just recently bought myself one, we both love them! Very comfy and comes with a bag of extra foam to add/remove from the pillow. The zipper on the side of the pillow cover is hidden but durable. We take it with us wherever we go, and always sleep so good.
