I'm passionate about quality sleep. I spent months testing pillows, and I'm reader-supported through purchases on Amazon.

In-depth Comparison (2024): Chamberlain Down Dual-Chamber Pillow vs. Coop Eden Pillow

I tested 14 different pillows over the course of six months. I slept on each pillow for at least five nights each. I rated each pillow based on how comfortable it was to sleep on over an extended period of time, whether or not the construction seemed high quality to me, and my take on suitability for different body types and sleep positions. Here is an in-depth comparison of the Chamberlain Down Dual-Chamber Pillow and Coop Eden Pillow.

Have you ever been surprised by how nice the pillows were in a luxury hotel or resort? As a Marriott Bonvoy Titanium Elite member for a few years in a row, I've stayed at many hotels, and the Chamberlain Down Dual-Chamber Pillow reminds me of some of the best hotel pillows I've experienced. It's made with the same type of design as the hotel pillows, featuring a down chamber on the outside wrapped around a feather chamber on the inside. I enjoy the satisfying puff of air from the down layer that allows me to "sink" into the pillow, and the feather chamber on the inside gives the pillow more structure than a typical down pillow. I tested three down and feather pillows for this review, and the Chamberlain Down pillow is by far the highest quality in my opinion.

The Chamberlain Down pillow is incredible for back-sleeping and stomach-sleeping.

Down pillows in general have been prized as luxury items for centuries. Down pillows function by trapping air inside the pillow. The air provides loft for the pillow, and the escaping air provides the buoyant sensation as the sleeper lies down. This makes down pillows different from pillows made with other materials, which provide loft through the material itself rather than trapped air. Feathers don't trap air as well as down, but they do provide loft through their structure thanks to the hard quill. Most pillows use a combination of down and feather since down can be very expensive, and having some structure can be an advantage to prevent the pillow from going flat over time.

The Chamberlain construction quality shows in two ways. First, the seams of the pillow are double-stitched, which prevents feathers and down from escaping the pillow. In contrast, the Puredown pillow is single-stitched along the seams. The Pacific Coast Double DownAround pillow has double-stitching, but the one I purchased has feathers sticking out of the stitching, as shown in the picture below. This is important because escaping down clusters might allow the pillow to go flat over time, and clusters in the air may cause unwanted sneezing.

The double-stitched seams of the Chamberlain Down pillow look more reliable to me relative to the seams of the other down and feather pillows.

Second, the Chamberlain Down pillow uses the aforementioned dual-chamber construction that wraps a layer of down on the outside, keeping the sleeper insulated from the feathers. This is the same build used in luxury hotel pillows. In fact, while multiple pillows that I tested for this review claim to be "hotel-style" pillows, the Chamberlain Dual-Chamber Pillow is the only one that reminds me of the pillows I've used at high-end hotels. Many years ago, I traveled for work, staying at hotels such as the Ritz Carlton, St. Regis, and Intercontinental, so I've become all too familiar with hotel pillows. The down layer on the outside prevents the sleeper from feeling any of the quills from feathers in the inner chamber, which results in the feeling of sleeping on air. The Chamberlain Down pillow has a substantial layer of down to achieve this effect. While I have felt quills in other down pillows, I do not feel any quills in the Chamberlain Down Dual-Chamber Pillow.

By comparison, the Puredown pillow, which is only a single chamber, mixes down and feathers together, and I can feel the quills in the pillow when I lie down. The Pacific Coast Double DownAround pillow is also a dual-chamber pillow, but when I lie down, I can still feel the quills. Even though the stated proportion of down is the same as the Chamberlain Down pillow, the Pacific Coast Double DownAround pillow uses 550 fill power down according to the Pacific Coast website at my time of purchase, while the Chamberlain Down Dual-Chamber Pillow uses 600+ fill power. In down terminology, a higher fill power indicates larger down clusters, which are better at trapping air. As a result, when I lie down on the Chamberlain Down pillow, the layer of down holds my head buoyant, but I sink straight into the feathers with the Pacific Coast pillow.

Like all down and feather pillows, the Chamberlain Down pillow will require fluffing in the morning. Fluffing just pumps the air back into the down clusters. At nicer hotels, fluffing typically happens during evening turn-down service. I find that my Chamberlain Down pillow is comparatively better at maintaining its air compared to the other down and feather pillows I have, so I don't mind fluffing when I sleep on it.

I classify the firmness as soft, but it's important to note that while the pillow feels soft, there is a substantial amount of material inside. When I lay my head down, I sink slowly but considerably into the pillow. Because the pillow has so much material, I still get that buoyant support. It's still not enough support for me to side-sleep comfortably, but the pillow is very comfortable for sleeping on my back or stomach. If you want a pillow that disappears underneath, this pillow has too much material for that to happen, but if you want a soft pillow that gives a slow-motion sinking sensation without completely disappearing, then this is the pillow to get.

For anyone searching for a luxury pillow similar to the ones found in high-end hotels, I highly recommend this pillow. The Chamberlain Down Dual-Chamber Pillow provides that signature sensation of sleeping on air, and it's great for back-sleepers and stomach-sleepers. I put this pillow in my guest bedroom, and at least half my guests comment on the Chamberlain pillow or ask where they can get their own.

Finally, this pillow is only available on chamberlaindown.com, which can sometimes run out of stock. I reached out to see if they sell on other marketplaces, but they told me that they tightly control their distribution. Sites like Amazon tried taking me to different pillows that did not have the same quality. If you're looking for a hotel-style pillow, I would recommend being patient and buying when you see Chamberlain Down in stock.

The Coop Home Goods Eden Pillow is an adjustable pillow similar to the Saybrook pillow. I really enjoy the sleep experience on the Coop at the start of the night, but it does have a few flaws that hold it back, including the way the polyester filling is tangled together inside the filling, the overall dominant feel of the polyester filling, and memory foam that doesn't feel like memory foam to me.

The Coop Eden Pillow is adjustable, which allows it to accommodate multiple sleep positions and body types.

The pillow is adjustable with shredded memory foam and polyester fiber inside. It arrives in a box with extra filling, which is a nice touch, though it comes overstuffed already. I doubt anyone would be adding additional filing. Personally, I took out about a quarter of the filling before sleeping on mine. The ability to micro-adjust the pillow loft to the perfect height gives this pillow a massive advantage over other pillows in contention without this feature. The Coop Eden Pillow is the higher priced pillow that Coop offers. They also offer the Coop Original pillow, which does not come with silicone gel, according to the Coop website.

The polyester fiber is different in the Coop pillow compared to the Saybrook pillow. The fibers are long and tangled throughout the pillow. There is also more polyester fiber in comparison. The result is that taking out filling from the Coop pillow requires ripping out chunks of entangled polyester fiber, similar to ripping apart large cotton balls. For the Coop Eden Pillow that I have, after I remove some filling, I have to shake the pillow vigorously in order to spread everything evenly again because the filling left inside the pillow is still tangled together. The experience has unnecessary friction.

The Coop Eden filling has more polyester fiber relative to the Saybrook Lion Down Alternative filling. Overall, it sleeps more like a polyester pillow for me.

I am underwhelmed by the quality of the foam. When I squeeze the foam between my fingers, it just seems like regular foam to me instead of memory foam. Instead of a slow motion compression, the foam collapses in real time, and I can visibly tell that the foam has looser air bubbles. The Coop foam brings to mind the foam used on Walkman over-the-ear headphones in the 80's or the foam of a sponge. As a result, my experience is that the foam provides less support compared to other memory foam pillows that I've tried. I find that my Coop pillow feels flatter by morning, and I don't feel as supported as I would like. Unfortunately, adding more filling in would make the pillow feel too lofty at the start of the night, so that wouldn't be a good solution to the problem. On the plus side, I do enjoy using the Coop pillow for stomach-sleeping.

Notice the larger air bubbles shown here in the Coop foam.

Because the proportion of polyester fibers is higher and because of the feel of the foam, the pillow overall sleeps more like a polyester pillow in my opinion. If you're looking for a polyester pillow, I would recommend the Coop Eden Pillow since it is adjustable. However, if you're looking for the feel of a memory foam pillow, then I'd recommend considering the other options.

Picking the right pillow can be important. I did all the research here to make the process easier. I hope that this blog helps you as you make your decision.
