Amazing pillow - adjustable filling
Team Name: Eden, Size: King, Color: Crescent
This pillow is AMAZING. My wife loves it. The crescent shape is cool and unique and enables your neck, back, and shoulders to lay better on the bed. My wife is a back sleeper and sometimes side sleeper. What’s amazing about this is you can adjust the quantity of the filling to your preference. It came with an extra bag if you want to fill it with more. We ended up taking a fair bit out. The card it comes with was super helpful illustrating how your head should rest on it, which showed my wife she had to take some out for her neck to be flatter. It seemed too firm at first so taking out the filling helped. The material inside is super fluffy, light, and airy- it’s extremely soft! As soft as down or other material. I mean this is an amazing pillow. It is luscious and super comfy. It is expensive but worth it.

I can't sleep without this pillow.
Team Name: Eden, Size: King, Color: Classic
This review is for the King size, adjustable Eden pillow. I bought the original years ago and somehow lost it when I moved recently, so I bought the Eden to replace it. Years ago, these pillows were not adjustable but I loved it anyway and was truly upset when I discovered it was missing. I actually lost sleep over it. When I found out they're adjustable now, I about lost my mind over the possibilities. In fact, I love the adjustable, Eden version so much that I bought another one. So yeah, I have purchased this pillow 3 times and have not been happier with any other pillow.
Bad news first. The odor.
You should know that they claim the foam is packed "fresh." This means there WILL be an odor when you receive it because it hasn't had the opportunity to air out. You'll have to do that yourself. Maybe they'll find a way in the future to "pre-air" the foam they use. For now, just accept that it's WORTH THE WAIT and really not a big deal. Don't return your pillow just because of the odor. It WILL go away and you don't want to miss out on this fantastic pillow. They suggest letting it sit for 24 hours or throw it in the dryer. Neither of these methods are long enough, in my opinion, but please be patient. I have experience with 3 of these pillows now and tried different techniques.
This is what works best for me: Upon arrival, I immediately remove the outer pillowcase and set aside. Over the course of 48 hours, I let it sit on the bed in my guest room with the ceiling fan on and I "fluff" it 3 or 4 times each day. (I will describe proper fluffing technique for shredded foam later) Then I throw it in the dryer on low for a full cycle. Then put the case back on and it's done! You'll never have to worry about that again and soon you won't even remember having to do it.
Now that THAT'S out of the way...
I love that these pillows are adjustable now. They really packed in the foam on the king size! I'm not kidding. There was so much foam in my pillows that they, frankly, were too heavy and way too firm for me. I've seen some negative reviews to the contrary. Maybe since then, they've increased the amount of foam they include (they should keep that up, if that's what happened). That's not how I like my pillows but some folks might be into that so I'm glad they put enough in there for those who need a lot of support. They do include 1/2 pound of extra foam in case you want a true, solid-as-a-rock feel. I do not. I'm a stomach and side sleeper, who likes more "squish" to my pillows, so I ended up removing so much foam from my 2 king size pillows that I have enough to make 2 standard sizes with the same squish factor. Not kidding. I went to the Coop website and purchased 2 standard liners and cases that I'm going to stuff with the excess foam and use on my guest bed. I anticipate some of my guests asking where I got the awesome pillows. :)
As we all know, memory foam holds heat too well and some foams will kick you right out of bed because you just can't stand to be that hot anymore. I did experience heat retention in the "original" that I had for years. I flipped the pillow over to get the cool side. I assumed all memory foam was like that so I put up with it. I don't get that at all with the Eden version. I'm a hot sleeper but I haven't had any issue with the Eden at all. The Eden has the blue foam in it that's gel-infused. I don't use anything extra or fancy to keep them cool. The foam is in the provided liners and pillowcases and I cover those with normal, cotton pillowcases.
I did see a couple reviews that claim their pillows went flat after a while. I'm confused by this. I had my first pillow for years and never experienced any change in texture. As with ANY shredded memory foam pillow, they need to be "fluffed" every now and then. In fact I fluff all of my pillows occasionally, regardless of the stuffing used (I have a variety of textures on my bed). But regardless, shredded memory foam pillows don't go flat. It's just not a thing. If you feel like it's flat, fluff it. Get rough with it. The shapes of the shreds can, over time, start to fit together like puzzle pieces and can become compact in some areas in the pillow. Maybe this is what creates the illusion that it's flat? "Fluffing" a shredded foam pillow involves breaking all the pieces up so they can move independently again. To achieve this, you have to grab several areas of the pillow with both hands so you have clumps of foam in your hands and then sort of jostle everything around in there, breaking up all the chunks. I usually grab and use the same motion I would use to bang cymbals together and then repeat all over the pillow until it feels like everything is separated again. I find this technique to be most effective when I grab around the edges. This takes only 5-8 seconds to accomplish and is completely normal maintenance for a shredded foam pillow.
Final thought: Shredded memory foam pillows are not for everyone because comfort is subjective. We all sleep differently and have different needs. After reading through some of the negative reviews, I've determined that some of them HAD to have been left by people who have never used a shredded foam pillow before and have determined it's not for them. COOP has a generous 100 night, no questions asked refund policy, so it doesn't hurt to try it. I don't view those reviews as a poor reflection of this company's products, but rather that the consumer tried something once and decided shredded foam pillows are not for them. I do have some experience with shredded foam pillows and can tell you that the Eden is, hands down, the best and highest quality that I've found on the market.

Great Pillow and Highly Adjustable
Team Name: Eden, Size: King, Color: Classic
I have used a Claritin Down Alternative Pillow in the past, but they are no longer available. I am very picky with my pillows and have had a difficult time finding one that fits my needs. I decided to purchase the Coop Pillow despite the high cost. After several weeks of use, I am glad I found this one. The pillow has just the right amount fluff and support. I like that it comes with extra fill that I can use to adjust the its firmness, but I didn't need it. I'm a side sleeper and it was great right out of the box. The outer shell of the pillow is soft and very good quality. I am so glad that I found an alternative to my Claritin Pillow.
The reason I only gave it 4 stars are for two simple reasons. First, the cost. This product is very comfortable, but there is no magic to its construction. The fill appears to be just finely shredded memory foam. The extra fill doesn't even come in a storage bag. It is wrapped in plastic. If you open it, you will need to find a separate storage container to put the excess fill. For this price, I would expect more. Second, this pillow is advertised as being "cool" to sleep on. However, I find it warmer than other pillows to the point it seems to trap heat. My wife has the standard Coop Pillow and I feel that it is "cooler" than this version. Of course, this is very subjective and you will need to test for yourself. Overall, this is a great pillow that has endless adjustability due to the extra fill provided. A pillow for everyone!

Quality & Comfort with Fully Adjustable Support
Team Name: Eden, Size: Queen, Color: Classic
I used to buy pricey, handmade, 100% down pillows—until I learned about the cruelty behind down production. I stopped using down entirely: pillows, comforters, jackets, everything. Then began the long search for something that could at least come close to the comfort of down, I tried Tempur and countless others, but nothing came close.
As a side sleeper, I need a pillow that’s high, SOFT, supportive, conforming, and huggable. After wasting money on at least five different pillows, I finally tried the Coop Home Goods Eden Pillow because of its adjustability. The cover is kind of thick, soft, and well‑made (I use a nice cotton pillow cover over it). The filling is soft and high quality. You can customize the height and firmness however you like. It even comes with plenty of extra fill.
To my surprise, the shredded foam doesn’t make the pillow clumpy—something every other similar pillow I tried struggled with. The surface stays smooth and soft, and it’s been a total game‑changer. It’s a keeper! I’ve had mine for almost four years now and only needed to add more filling once, about 8–10 months ago. Toss it in the dryer on low with a couple of tennis balls, and it fluffs up like new. And the icing on the cake: outstanding customer service.
I highly recommend this pillow and will definitely buy it again
