In-depth Comparison (2024): Tempur-Pedic Tempur-Cloud Pillow vs. Casper Original Pillow

Solid Memory Foam

The Tempur-Pedic Tempur-Cloud Pillow is a solid memory foam pillow, which means the loft isn't adjustable. The Tempur-Pedic memory foam is also incredibly soft. For side-sleepers and back-sleepers, this memory foam will likely be too soft in my opinion. For stomach sleepers, who might prefer a thinner and softer pillow, the Tempur-Pedic works perfectly.

The quality of the memory foam is noticeable. When compressed all the way down, the Tempur-Pedic memory foam takes about 3 seconds to bounce back to the original shape, as if it were bouncing back in slow motion.

The foam is much softer compared to the Weekender and Pillow Cube, which are also solid memory foam pillows. I measure all three of these solid memory foam pillows at a 5-inch starting loft. When I lay my head down, the Tempur-Pedic compresses halfway while the Weekender compresses only slightly and the Pillow Cube barely has any noticeable compression, so the Tempur-Pedic ends up effectively thinner. The compression provides a very comfortable sinking feeling for people who enjoy that aspect of a pillow.

I've slept on the Tempur-Pedic pillow in all three positions. As a side-sleeper and back-sleeper, this pillow does not provide enough support for my preferences. My head just sinks down. However, this pillow feels like magic when sleeping on my stomach. I usually hug the pillow vertically so that half my body is on top of the pillow. The Tempur-Pedic will compress more for my body than my head, which is lighter, and the result is a very comfortable incline.

The pillow has a removable cover that feels well-constructed. Where the Weekender and Pillow Cube covers are thin by comparison, the Tempur-Pedic pillow cover is best described as substantial. Based on the feel of the memory foam and the feel of the pillow cover, I'd consider the Tempur-Pedic to have a higher quality construction compared to the Weekender and Pillow Cube.

I highly recommend this option for stomach sleepers. Side-sleepers and back-sleepers, though, need to be aware that this pillow won't have the support they might expect. I see mixed reviews for this pillow, and I suspect it's because the five-star reviews are more likely to be stomach sleepers who prefer a thinner pillow while the one-star reviews are more likely to be side-sleepers and back-sleepers.

Polyester Fiber (Down Alternative)

The Casper Original Pillow uses a pillow-in-pillow design with two layers, both made of polyester fiber, at slightly different firmness levels. This creates a thick but soft pillow that is great for back-sleepers who want a polyester fiber pillow. However, I don't recommend this pillow for side-sleepers due to the lack of adjustability: the thickness combined with the softness results in an unpredictable loft.

The most noticeable aspect of the Casper pillow is the loft: I measure it at 10 inches thick, the highest loft of any pillow tested. This is because the pillow is actually made up of a regular sized pillow covered by another layer of pillow. The outer layer can be unzipped to reveal the inner pillow sandwiched inside. The outer layer is extremely soft and thin. It resembles a comforter or a thick blanket. In fact, the pillow does remind me of a regular pillow wrapped in a comforter. The outer layer sinks completely in when used.

Unzipping the outer pillow reveals an inner pillow also made with polyester filling. Keep in mind that though the pillow can be unzipped, the filling cannot be adjusted. Unzipping doesn't give access to the filling. It only gives access to the inner pillow. While you can technically have three different lofts by sleeping on the inside pillow by itself, the outside layer by itself, and both layers combined, I wouldn't consider the pillow to be adjustable. I suspect most people will be sleeping on the pillow with all the layers together because either layer by itself is too thin for my preferences. Like the outer layer, the inner pillow sinks all the way down when I lay my head on it by itself. Based on my experience, neither the inner pillow nor the outer pillow will provide enough support for side-sleepers or back-sleepers individually. Theoretically, the inner pillow could be used for stomach-sleeping, but there are other options on the market that don't involve discarding half the pillow.

When used together, the pillows start at the full 10-inch-high loft. Laying my head down makes the pillow significantly thinner since both parts of the pillow are so soft. The inner pillow and the outer pillow compress all the way down when slept on individually, but the combined pillow does leave some loft simply because there is so much material. Unfortunately, as a side-sleeper, the loft feels slightly off for me, leaving my head angled uncomfortably. It's possible that some side-sleepers will find the loft level perfect, but I recommend that side-sleepers stick with a fully adjustable pillow like the Saybrook or Coop.

The Casper pillow and Sleepgram pillow share a lot of similarities. From the outside, they even look almost the same except for the different logos. There are three main differences, though. First, the Sleepgram pillow comes with two inner pillows. Despite this, both the Casper and Sleepgram pillows have the same loft, so the Sleepgram inner pillows are individually thinner compared to the Casper inner pillow. Second, the zipper on the Casper pillow feels to me like it's easier to operate compared to the zipper on the Sleepgram pillow, which contributes to my perception that the Casper pillow has higher quality construction. Finally, I find the Sleepgram pillow to be even softer than the Casper pillow. My head sinks down even more with the Sleepgram pillow. This is because the Sleepgram polyester filling glides more easily, so some of the material moves out of the way when I lay my head on it. The Casper pillow polyester fill is also soft, but it stays underneath my head, so even though it compresses, the material stays there to provide some loft.

Unlike some of the other pillows reviewed, the Casper pillow doesn't come with a separate cover. Inserting this pillow into a pillow case can be difficult due to the thickness. Though the pillow compresses easily when sleeping on it, getting it to compress from 365 degrees to shove inside a pillow case is relatively frustrating. It is far from impossible, but it does take more energy than it should. I find that when pillows are difficult to insert into pillow cases, I subconsciously avoid wash cycles.

The lack of adjustability makes the Casper pillow a non-starter for side-sleepers since the angle of the head is so important and everyone has a different shoulder and head size. For back-sleepers looking for a polyester fiber pillow, the Casper pillow is a great choice. Because of the thickness, even though the pillow sinks significantly, it still provides some support.
