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

Down and Feather

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.

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.

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.

Shredded Memory Foam and Polyfiber Mix

On paper, the Wondersleep Premium Adjustable Pillow should be similar to the Saybrook and Coop pillows: it has shredded memory foam and polyester filling. However, that's where the similarities end. I selected this candidate because it was much cheaper than the other pillows while sporting the same reported features. I wanted to see what the difference was in person. Unfortunately, the pillow case quality, the adjustability, and the filling comfort level don't match up in my opinion.

Immediately upon unpacking, I notice the pillow has much less filling compared to other pillows and is very thin. The thinness of the pillow defeats the purpose of the adjustability because it won't be in the loft range many people need. The loft might be okay for stomach sleepers who appreciate a thinner pillow. Though the initial loft measures at 6 inches, the pillow compresses a third of the way down for me when I lie down due to the softness.

The sensation of the Wondersleep pillow fill is dominated by polyester fiber for me, with pieces of shredded memory foam buried throughout. The memory foam feels stiff, not just firm, as if it had been left out in the sun too long. The pillow reminds me of clumps of cattail fluff in the wild: mostly soft and fluffy but with random bits of hard seeds (or in this case, memory foam) inside.

Though many shredded memory foam pillows under $50 can look similar to the Saybrook and Coop pillows on paper, I recommend investing more to get the higher quality construction and better filling found in the top picks.
