Choosing a pillow is less about finding a single “best” option and more about matching the right design to your neck, shoulders, sleep position, and temperature needs. In this 2026 seven-night comparison, reviewers tested two popular picks with very different strengths:
- Derila Ergo (Editor’s Choice, 4.8): an ergonomic memory-foam pillow engineered for proper spinal alignment and neck-pain relief, especially for side and back sleepers.
- Cloudpillo Original (Best Budget Luxury, 4.3): an adjustable, temperature-regulating, all-season pillow designed to shape to your sleeping position with customizable loft.
The headline outcome from the seven-night test is a clear use-case split: Derila Ergo consistently delivered stronger cradle-and-alignment support (a big win for side and back sleepers dealing with neck issues), while Cloudpillo Original stood out for loft customization, plush hotel-style comfort, and season-spanning temperature control. Below, we’ll break down what that means in practice—category by category—so you can buy based on how you actually sleep.
At-a-Glance Verdict
If you want the fastest shortcut to the right choice, start here:
- Pick Derila Ergo if you want structured support that encourages better neck and spine alignment, especially if you are a side sleeper or back sleeper with recurring neck discomfort.
- Pick Cloudpillo Original if you want adjustable loft (to fine-tune height and feel), a plush “hotel pillow” vibe, and a design aimed at all-season temperature regulation.
What the Seven-Night Test Focused On
To keep this comparison useful for real shopping decisions, reviewers focused on the performance areas most people notice immediately—then reassessed them after several nights, not just a quick first impression.
Testing criteria used in the comparison
- Support and alignment: how well the pillow helps keep the head and neck in a neutral position (especially for side and back sleepers).
- Loft adjustability: how easily sleepers can change pillow height to match shoulder width, mattress softness, and personal preference.
- Cooling performance: whether the pillow feels temperature-neutral or actively better at avoiding heat buildup across the night.
- Firmness and feel: perceived firmness (not a lab ILD measurement), plus how the pillow compresses and rebounds.
- Suitability for side and back sleepers: how reliably each design supports these two positions through normal repositioning.
Because individual comfort is personal, the test emphasizes repeatable patterns observed over seven nights—like whether support “holds up” after a few nights and whether temperature comfort stays consistent from bedtime to morning.
Derila Ergo: What It Did Best in the Seven-Night Test
Derila Ergo is positioned as an ergonomic memory-foam pillow (see derila pillow amazon) designed for proper spinal alignment. In the seven-night comparison, its biggest advantage was consistent, structured support—particularly valuable for sleepers who wake up with neck tightness or feel like their pillow lets their head “sink” out of alignment.
Key benefits reviewers highlighted
- Stronger cradle-and-alignment support: Memory foam contouring helped keep the head and neck supported rather than collapsing over the night.
- Ideal for side and back sleepers with neck issues: The ergonomic intent showed up in how stable the head position felt night after night.
- Stable shape through the week: Testers looking for a “set it and forget it” support profile tended to prefer Derila Ergo.
Firmness and feel (practical description)
Reviewers generally experienced Derila Ergo as supportive with a contoured cradle—the kind of feel that prioritizes alignment over a purely plush, hotel-like sink. If your main goal is reducing the sense that your neck is “hanging” or over-angled, this structured feel is often a positive.
Who tends to love Derila Ergo
- Side sleepers who want consistent neck support and a more locked-in head position.
- Back sleepers who want a pillow that helps maintain neutral posture rather than over-elevating the chin.
- Shoppers who value support consistency more than adjustability.
Cloudpillo Original: What It Did Best in the Seven-Night Test
Cloudpillo Original is best known here for two shopper-friendly wins: customizable loft and an all-season, temperature-regulating build. In the seven-night comparison, that translated to a pillow that could be tuned to suit different body types and comfort preferences—while staying comfortable across changing bedroom temperatures.
Key benefits reviewers highlighted
- Customizable loft: The ability to adjust height made it easier for testers to dial in comfort based on shoulder width and sleeping position.
- Plush hotel-style comfort: Many sleepers associate “luxury” with a softer, more cloud-like surface feel, and Cloudpillo Original leaned into that experience.
- Season-spanning temperature control: Reviewers recognized the temperature-regulating intent as a practical advantage for year-round use.
Firmness and feel (practical description)
Cloudpillo Original came across as plusher and more adaptable in feel, with comfort that can be tuned through loft adjustment. For shoppers who dislike a “locked-in” ergonomic contour and prefer a pillow that can be shaped to their position, that adjustability is the main event.
Who tends to love Cloudpillo Original
- Sleepers who want to fine-tune pillow height rather than commit to one profile.
- People who prefer a softer, hotel-style comfort feel.
- Shoppers who care about temperature comfort across seasons (not just in summer).
Head-to-Head Comparison: Support, Loft, Cooling, Firmness, and Fit
Here’s a clear side-by-side summary based on the comparison’s focus areas and seven-night observations.
| Category | Derila Ergo (Editor’s Choice, 4.8) | Cloudpillo Original (Best Budget Luxury, 4.3) |
|---|---|---|
| Support and alignment | Stronger cradle-and-alignment support; designed for spinal alignment and neck-pain relief. | Support depends on how you adjust loft; comfort-first feel with adaptable shaping. |
| Loft adjustability | More “set profile” ergonomic approach; best for people who want consistent support without ongoing tuning. | Standout strength; customizable loft makes it easier to match your body and mattress. |
| Cooling performance | More temperature-neutral, with primary emphasis on support and alignment rather than all-season thermal engineering. | Clear advantage for all-season temperature regulation; designed to stay comfortable across changing temps. |
| Firmness and feel | Supportive, contoured, stability-forward; prioritizes posture over plushness. | Plush, hotel-style comfort with adjustable height to change perceived firmness. |
| Side sleeper fit | Excellent for side sleepers seeking neck support and a consistent cradle. | Great if you want to adjust loft for shoulder width; comfort can be tuned. |
| Back sleeper fit | Excellent for back sleepers focused on neutral alignment and steady support. | Good for back sleepers who want to adjust height carefully to avoid over-elevation. |
Seven-Night Takeaways by Sleep Position
For side sleepers
Side sleeping usually requires enough loft and structure to fill the gap between the head and shoulder—without forcing the head to tilt up or down. In the seven-night comparison:
- Derila Ergo impressed reviewers who wanted a more “guided” alignment feel, particularly those sensitive to neck strain.
- Cloudpillo Original shined for side sleepers who want to customize loft until the shoulder-to-neck gap feels just right.
Practical rule: if you want built-in alignment structure, lean Derila. If you want control over height, lean Cloudpillo.
For back sleepers
Back sleepers often do best with a pillow that supports the natural curve of the neck without pushing the head too far forward. Over seven nights:
- Derila Ergo tended to feel more reliable for maintaining a neutral head position across the week.
- Cloudpillo Original worked well when testers adjusted loft to avoid excessive elevation and maintain comfort.
If you frequently wake up feeling like your neck needs “resetting,” the structured support of Derila Ergo may be the more direct match. If you prefer a softer feel and want the ability to fine-tune height, Cloudpillo Original can be a strong fit.
Seven-Night Takeaways by Temperature Preference
If you sleep warm or want all-season comfort
Thermal comfort can make or break sleep quality—especially if you wake up flipping the pillow for a cooler side. In this comparison, Cloudpillo Original clearly owned the temperature-regulating narrative, with reviewers highlighting its season-spanning design intent.
That makes Cloudpillo Original a compelling pick if you want one pillow that feels comfortable through summer nights and winter heating—without constantly chasing the “cool spot.”
If support is your top priority (even over cooling)
Derila Ergo is the option to prioritize when your main goal is waking up with a better-feeling neck and a more supported posture. While many sleepers find memory foam comfortable, this pillow’s defining advantage in the seven-night test was alignment-driven support rather than a cooling-first feature set.
How to Choose Between Them (Simple Decision Guide)
Use these quick checkpoints to make a confident choice without overthinking the specs.
Choose Derila Ergo if you want:
- Editor’s Choice performance (4.8) focused on alignment

What “Firmness” Really Means Here (and Why It Matters)
In pillow shopping, firmness isn’t just a comfort preference—it affects alignment. In this seven-night comparison, firmness differences showed up in two practical ways:
- Derila Ergo: A more supportive, contour-forward feel that helps keep head and neck positioning consistent. This often benefits sleepers who feel better when their pillow “holds them up” instead of compressing too far.
- Cloudpillo Original: A plusher feel that can be adjusted through loft changes, letting you move along a comfort spectrum. This is ideal if you want a softer surface but still need enough height to maintain posture.
If you’ve ever tried a pillow that felt amazing at bedtime but caused soreness by morning, this is usually why: the pillow compresses differently across the night. That’s exactly why a seven-night comparison is helpful—the pattern becomes clearer after repeated sleep cycles.
Bottom Line: The Best Choice Depends on Your Primary Goal
The 2026 seven-night comparison makes the decision refreshingly straightforward:
- Derila Ergo is the stronger pick when you want support, cradle, and alignment as your top outcomes—especially for side and back sleepers with neck discomfort.
- Cloudpillo Original is the smarter pick when you want adjustable loft, a plush luxury feel, and all-season temperature regulation that adapts to how you sleep.
Both pillows can improve sleep comfort, but they win in different ways. Choose the one that matches the problem you’re trying to solve: posture support (Derila Ergo) or custom comfort and thermal balance (Cloudpillo Original).
