The Dosaze Hybrid Adjustable Pillow was the only adjustable pillow I tested where I felt a clear difference in both support and comfort. I also loved how the multi-layer design included adjustable filling, which allowed me to fine-tune the firmness to exactly what I needed for each night. The combination of adjustability and support made this pillow my clear favorite.

Each feature on its own was great, but together they really made this pillow stand out from the competition. I was genuinely impressed with how customizable it was. Most of the other pillows I tried only focused on one or two features, but the pillow I chose combined adjustable fill, firm core support, and some fantastic cooling options, creating a truly versatile pillow package.

The regular pillow worked perfect, but Dosaze is also offering a cooling cover that makes this one of our favorite cooling pillows we’ve tested as well. Or, you could just purchase the Thermacool cooling pillowcase on its own.

This pillow also works for back, side, stomach, or combination sleepers. The supportive core keeps your head and neck aligned, reducing neck and back discomfort. It gave just the right amount of structure, so it felt soft yet solid—no sinking through the pillow!

On top of that, the adjustable fill made the pillow feel super plush and comfortable. It offered the perfect blend of softness and support, similar to a neck-pain-reducing pillow but with added flexibility. The fill could be added or removed to customize the height and firmness to your liking. While some other brands (like Coop) offer similar adjustability, the firm core of this pillow provided much-needed stability, which kept it from feeling too soft or unbalanced. I was thoroughly impressed.

All of this together earned the Dosaze Hybrid Adjustable Pillow our top spot!

The Coop is one of our other well-reviewed pillows that has gained a lot of popularity recently, and it was one of the best we slept on. We loved the cooling gel-infused memory foam and the adjustability it offered (although it’s standard fill was just fine for us).

Coop has a few pillows, and the Eden (the one we tested) has an adjustable fill. The fill is a “cooling gel-infused” foam that is designed to help promote inner cooling and wick away heat. Overall, we thought the pillow provided decent cooling. Our main issue with the Coop was that the fill (which is mostly microfiber) tended to feel floppy and flat at times and not particularly structural.

We think the SlumberCloud UltraCool Pillow is a great option to consider. Using what they claim is “NASA-inspired technology,” the SlumberCloud is a down alternative with lots of loft. Unlike previous versions, the new Adjustable UltraCool Pillow offers customizable firmness with two inserts and zippered gussets, blending squishy fiberfill with supportive memory foam for a tailored sleep experience.

Our main issue with this pillow is that it doesn’t offer full adjustability, as you only have the ability to add or remove one of the inserts and not incrementally change the fill.

The Silk & Snow pillow is technically a hybrid. We liked the down-alternative microfiber fill since we could customize it. The reason I say “technically” a hybrid, however, is that it isn’t a solid core. The core is a firmer memory foam core, so it doesn’t provide as much structure as some of the other pillows for real cores made of solid memory foam did.

Still, it was decently priced and we enjoyed it. The only other major drawback was that there wasn’t anything particularly cooling about this pillow, so it does lose some value and comfort on those metrics.

The MyPillow, flatly, isn’t a great adjustable pillow. Generally, we didn’t love the MyPillow for a few reasons. First, it has another one of those gimmicky-feeling features (similar to the Marlow pillow), only this time in the form of “interlocking foam pieces.” They market irregular pieces of foam as an interlocking structure that creates something rigid when it just doesn’t really work that way in reality.

All that being said, we did include the MyPillow on this list, even though it isn’t technically an adjustable pillow. They do advertise it as an adjustable pillow, however, specifically the MyPillow 2.0. What they mean is just that the pillow comes in different fill levels, from Lower Loft to Most Loft. While this is nice, it doesn’t really compare to having the ability to adjust your pillow yourself, and it also doesn’t come with a supportive core.

Unlike most of their products, Purple didn’t opt for latex in their pillow. Overall, we liked this pillow a lot. Inside, Purple used a proprietary Moon Foam to mold to your head, and this is fully adjustable. Additionally, they added neck roll chambers for edge support, and these are optional.

Purple is famous for its honeycomb design on all of its products, and the Free Form also includes it. They claim it helps to distribute weight, but in this format, it’s more of a way to distribute the cooling gell across the pillow. The outer cover on the pillow is thin and breathable, so the cooling gel inside the honeycomb really does all the heavy lifting here regarding cooling power.

While we did love the pillow, it is hard to really recommend it. The King-sized pillow costs $240, which probably makes it the most expensive pillow I’ve ever seen before. This is packed with features, but overall gets a low value score due to the price.

The Marlow Pillow was mediocre, in our opinion, and one of the features seemed like a marketing gimmick and not a real feature.

First, the company doesn’t prioritize cooling as a main feature of this pillow. Instead, they treat it as a cool (pun intended) bonus feature. The cooling mechanism is described as a gel-infused memory foam and a breathable cover, which are all okay.

The real “silly” feeling aspect of this pillow was how they hyped up what amounted to a zipper. First, the addition of a zipper on the side of the pillow “for airflow” doesn’t really generate an internal breeze like they would have you believe. Second, Marlow also asserts that opening the zippers is the best way to adjust the loft of the pillow itself. Opening the zipper makes it fluffier, and closing it makes it denser. In reality, this would just compress the pillow before your head even hits it, so it’s just not doing anything.

We would pass on this as an adjustable pillow for those reasons.
