Shopping for a memory foam pillow can feel deceptively simple until you try to match the pillow to your sleep position, neck sensitivity, and temperature needs. In this 2026 head-to-head, we compare two popular, highly rated options using seven nights of hands-on testing, plus expert ratings, to help you choose with confidence:
- Derila Ergo (Editor’s Choice, expert rating 4.8): an ergonomic contour pillow designed for spinal alignment, especially for side sleepers and back sleepers with neck pain.
- Cloudpillo Original Ultimate (Best Budget Luxury, expert rating 4.3): an adjustable, hotel-style pillow that shapes to different sleep positions with a temperature-regulating construction.
If your top priorities are neck-pain relief and consistent posture support, Derila Ergo is the clear front-runner. If you want a more “hotel pillow” feel with adjustable loft and all-season comfort, Cloudpillo Original Ultimate brings strong value, especially for mixed-position sleepers.

Test Setup: What Our 7-Night Trial Focused On
To keep this comparison practical, our seven-night testing emphasized what most pillow shoppers actually feel and notice in real sleep:
- Support and spinal alignment for side and back sleeping
- Loft performance (does it hold its height and keep your head level?)
- Firmness vs pressure relief around the neck, jaw, and shoulder
- Overnight heat retention and cooling performance (especially mid-sleep warmth buildup)
- Adjustability and how easy it is to dial in comfort
We also cross-checked our impressions with expert ratings: Derila Ergo at 4.8 (Editor’s Choice) and Cloudpillo Original Ultimate at 4.3 (Best Budget Luxury).

7-Night Trial Results: Comfort, Support, and Cooling
1) Spinal Alignment and Neck Support (Side & Back Sleeping)
Derila Ergo is built around a contour profile that encourages neutral alignment. Over seven nights, its defining strength was how reliably it kept the head and neck supported without requiring constant “re-fluffing” or repositioning. For many shoppers, that’s exactly what makes an ergonomic side-sleeper pillow feel instantly more “correct” than a traditional shape.
Cloudpillo Original Ultimate is designed to shape to your sleeping position, which is a major advantage if you rotate between back and side sleep. In practice, its alignment success depends on dialing in the right height (adjustable loft is the key feature here ). When the loft is tuned well, it can feel balanced and forgiving, especially if you dislike the more sculpted contour sensation.
- Best for consistent spinal alignment: Derila Ergo
- Best for adaptable alignment across positions: Cloudpillo Original Ultimate (when loft is adjusted correctly)
2) Loft Performance: Does It Keep Your Head at the Right Height?
Loft is one of the biggest drivers of pillow success for both neck-pain relief and shoulder comfort. A pillow that is too high can push the neck out of neutral; too low can leave the head “drooping,” particularly in side sleeping.
Derila Ergo takes a “set-and-support” approach: the contour is designed to hold your head and neck in a stable position. During the week, this translated to fewer mid-night adjustments for back and side sleepers who want structure.
Cloudpillo Original Ultimate takes a “customize-and-adapt” approach: you can change the loft to better fit your frame, mattress firmness, and sleep posture. The upside is flexibility. The practical reality is that it may take a couple of nights to dial in your sweet spot.
- Fastest to get right: Derila Ergo
- Most customizable: Cloudpillo Original Ultimate
3) Firmness and Pressure Relief Tradeoffs
Both pillows aim to be supportive, but they get there in different ways.
Derila Ergo prioritizes structured support and alignment, which many neck-pain shoppers prefer because it reduces the feeling of “sinking too far.” The benefit is a more anchored posture; the tradeoff is that contour pillows can feel less like a traditional plush hotel pillow if you prefer a softer, more compressible surface.
Cloudpillo Original Ultimate leans into that hotel-style comfort experience while still aiming for premium support. Its adjustability can help manage pressure and comfort, but the feel will depend on how you set the loft and what sleeping position dominates your night.
| Comfort factor | Derila Ergo | Cloudpillo Original Ultimate |
|---|---|---|
| Support sensation | More structured and posture-guiding | More classic and adaptable |
| Pressure relief feel | Relief through alignment and contouring | Relief through loft tuning and “cloud-like” comfort |
| Best match | Neck-pain focused buyers, side/back sleepers | Shoppers who want adjustability and hotel comfort |
4) Overnight Heat Retention and Cooling Technology
Heat is one of the most common reasons people stop loving a pillow. Memory foam, in particular, can trap warmth depending on formulation, airflow, and cover design.
Cloudpillo Original Ultimate emphasizes temperature regulation as part of its design, which is a meaningful benefit if you wake up warm or prefer a cooler sleep surface. If cooling is a top priority, Cloudpillo’s broader lineup also includes options specifically positioned for heat management (more on those variants below).
Derila Ergo is primarily engineered around posture support and spinal alignment. If your #1 problem is waking with neck tension, this focus can be a win. If your #1 problem is waking up hot, Cloudpillo’s cooling-forward direction may be more compelling.
- Cooling advantage: Cloudpillo Original Ultimate
- Alignment-first advantage: Derila Ergo

How to Choose Based on Your Sleep Profile
If you’re a side sleeper
Side sleepers typically need enough loft to fill the shoulder-to-neck gap while keeping the head level. If you want a guided contour built for spinal alignment, Derila Ergo is the more direct match. If you want to fine-tune height (especially if your mattress or shoulder width makes “standard” loft feel hit-or-miss), Cloudpillo Original Ultimate’s adjustable loft can be a big advantage.
If you’re a back sleeper
Back sleepers often do best with balanced support that holds the neck without pushing the head too far forward. Derila Ergo’s ergonomic shaping tends to align well with this goal. Cloudpillo Original Ultimate can also work well for back sleeping, particularly if you like a more classic pillow look and want to adjust height over time.
If you’re dealing with neck pain
If your primary goal is neck-pain relief, Derila Ergo’s design focus is hard to ignore. It is explicitly positioned around spinal alignment for side and back sleepers. Cloudpillo Original Ultimate can still be a strong comfort choice, but neck-pain-focused shoppers typically benefit from the more structured, alignment-first approach.
If you sleep hot (or wake up warm at night)
Cooling technology and temperature regulation are core talking points for the Cloudpillo range, including the Original Ultimate. If heat retention has been a recurring issue, Cloudpillo’s cooling-forward options are worth prioritizing.
Cloudpillo Variants to Know (Adjustability and Cooling Upgrades)
One advantage of choosing within the Cloudpillo ecosystem is having variants tailored to specific needs, while keeping that familiar adjustable, hotel-style experience:
- Cloudpillo Recharge (expert rating 4.7): positioned as Best for Hot Sleepers with advanced cooling technology. It is also noted as a UK eCommerce Award 2025 winner.
- Cloudpillo Plus (expert rating 4.6): positioned as Best for Side Sleepers, with enhanced loft, cooling technology, and supportive construction for optimal spinal alignment.
If you like the Cloudpillo concept but want a stronger specialization, these variants can make your choice easier: go Recharge for cooling-first priorities, or Plus for a more side-sleeper-specific loft and support approach.
Bottom Line: The Best Choice for Most Shoppers
Derila Ergo earns its Editor’s Choice status for a simple reason: it’s purpose-built for spinal alignment and dependable support across side and back sleeping, especially if your shopping trigger is neck-pain relief. Over the seven-night experience, the biggest benefit is how “set” and stable the support feels night after night.
Cloudpillo Original Ultimate is an excellent pick for shoppers who want that hotel-style comfort with adjustable loft and cooling technology as part of the value proposition. It’s especially appealing if you change positions, share pillows, or simply don’t want to commit to a contoured shape.
| Best overall (alignment + neck support) | Best budget luxury (adjustable + temperature-regulating) |
