In-depth Comparison (2024): Coop Eden Pillow vs. Sleepgram Adjustable 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 Coop Eden Pillow and Sleepgram Adjustable Pillow.

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 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.
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.
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.
Sleepgram Adjustable Pillow
Polyester Fiber (Down Alternative)
- Extra soft
- A few configuration options exist
- Great for stomach-sleepers
- Not fully adjustable
- May be hard to fit into pillow case
- Premium price
- For side-sleepers, unlikely to get desired loft
- My head sinks down too much for my liking
The Sleepgram Adjustable Pillow is an extra soft polyester fiber pillow with a thick starting loft. Though nominally adjustable based on the pillow-in-pillow design that allows the sleeper to keep or remove two layers of inner pillows, I wouldn't consider the Sleepgram pillow fully adjustable because of the softness, which limits its appeal for those who want more support, and the inability to do micro-adjustments. The Sleepgram pillow can be a good option for stomach-sleepers, but I would not recommend it for side-sleepers and back-sleepers.
The Sleepgram pillow uses a pillow-in-pillow design similar to the Casper pillow. In fact, when I first unboxed the pillows, I thought they were the same pillow with different logos. However, on a closer look, I found three main differences. The first difference is the softness of the pillows. Both pillows have the same starting loft, but my head sinks in more when I sleep on the Sleepgram pillow compared to the Casper pillow. The Casper pillow is already so soft that my head sinks significantly, so I was surprised that the Sleepgram pillow had even less support. Even though the Sleepgram pillow starts at 10 inches of loft by my measurements, my head sinks so far into the pillow that I feel even less support than I get from pillows that start at half that loft. I would guess the difference between the Casper and Sleepgram softness comes from the friction in the polyester fibers. The Sleepgram polyester fibers glide very smoothly against each other, almost like silk strands. This means that the material appears to move to the side when I lay my head on the pillow. The Casper polyester fibers are also soft in terms of firmness, but they aren't as soft in terms of friction. Because of the softness of the Sleepgram pillow, I'm unable to get the support I need for side-sleeping, and this is one of the reasons I wouldn't consider the Sleepgram pillow fully adjustable.
The second difference is the number of inner pillows. The Sleepgram pillow has two inner pillows while the Casper pillow only has one. Nevertheless, the total starting loft is the same across the Sleepgram and Casper pillows as far as I can measure, so the Sleepgram inner pillows are individually thinner than the Casper inner pillow. I find this to be an advantage for the Sleepgram pillow because it does allow for more configuration options. Sleepgram labels one inner pillow with a blue tag and the other with a red tag. The instruction booklet that comes with the pillow says that the inner pillow with the blue tag is softer than the one with the red tag, so you can get different firmness levels by keeping different configurations of the two inner pillows. Because I can't get the support I need for side-sleeping on the Sleepgram pillow even with both inner pillows loaded inside, I tend to prefer stomach-sleeping when I use it. For stomach-sleeping, I'll remove the inner pillow with the blue tag. Though I appreciate the configuration options, I still prefer the ability to micro-adjust with the Saybrook and Coop pillows.
Finally, the zipper on the Casper pillow that I purchased feels significantly easier to operate for me compared to the zipper on the Sleepgram pillow that I purchased. This contributes to my overall perception that the Casper pillow has higher quality construction.
For stomach-sleepers who might want to try out different loft levels on the softer end of the spectrum, the Sleepgram pillow can be a good option. For side-sleepers, I'd recommend 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.
