Derila Pillow for Back Sleepers: Does the Central Groove Work?
Back sleeping is the second most common sleep position and, from a spinal alignment perspective, one of the best — when supported by the right pillow. The problem is that most pillows are either too thick (pushing the head forward and straining the cervical spine) or too flat (leaving the neck unsupported and causing the head to tilt backward).
The Derila Ergo Pillow’s central groove is specifically designed for back sleepers. We tested it over 8 weeks with two people who primarily sleep on their backs to assess whether the design actually delivers better cervical alignment and reduced morning stiffness.
What Back Sleepers Need From a Pillow
When lying on your back, the cervical spine should maintain its natural inward curve (lordosis). A pillow that is too high pushes the chin toward the chest — straining the posterior neck muscles and the C4–C7 disc spaces. A pillow that is too low lets the head fall back, compressing the facet joints of the upper cervical spine.
The ideal back-sleeper pillow has a moderate loft (typically 8–11 cm) and supports the natural curve under the neck rather than just cushioning the back of the head. This is what the Derila’s central groove is designed to do — the slightly lower, curved center cradles the neck in its natural lordotic curve while supporting the occiput (base of the skull) at the correct height.
How the Derila Contour Works for Back Sleepers
The Derila’s wave profile has a lower central section flanked by two higher side sections. For back sleepers, the central section is the primary contact zone. The slight concavity of the center:
- Keeps the head at a neutral height above the mattress
- Fills the cervical curve rather than letting it hang unsupported
- Prevents the head from rolling excessively to one side during the night
- Distributes pressure away from a single point at the back of the skull
The memory foam construction means the pillow conforms to individual neck curve variation — which is significant because cervical lordosis varies considerably between people. A pillow that fills the curve for one person may not for another; the pressure-responsive memory foam self-adjusts within the first few minutes of contact.
Our 8-Week Back Sleeper Test
Tester 1 — Karen, 55 (Chronic Back Sleeper, Upper Neck Pain)
Karen sleeps on her back and had been waking with upper neck and occipital pain 3–4 mornings per week. She used a standard medium-firm pillow before the test.
Week 1: Found the central groove “unusual but comfortable.” Pain on waking unchanged at first, though she noticed less tension at the base of her skull.
Week 3: Morning neck pain frequency dropped from 4 mornings to 2 mornings per week. Duration of morning stiffness shortened from 20+ minutes to 8 minutes.
Week 6: Pain on waking down to 1–2 mornings per week. Self-rated sleep quality up from 6/10 to 8/10. She noted waking with less tension headaches — which she hadn’t connected to pillow use before.
Week 8: Morning pain now occasional (1x per week or less). Karen reported the pillow “feels the same as when I first got it” — no noticeable compression loss in the center groove.
Tester 2 — Tom, 41 (Back Sleeper, Mild Sleep Apnea History)
Tom primarily sleeps on his back and has a history of mild positional sleep apnea. His focus was on whether the Derila’s positioning helped maintain better head and neck alignment throughout the night.
Week 1–2: Noticed he was staying on his back more consistently rather than shifting to his side partway through the night. The central groove provided enough passive stability to discourage head rolling.
Week 4: Morning grogginess — which he associated with disrupted breathing position — reduced noticeably. He was not using any sleep tracking device, so this is subjective, but he reported feeling more rested consistently.
Week 8: Continued to sleep primarily on his back. No neck pain during the test. He noted the pillow’s cooling cover as a consistent positive given he tends to sleep warm.
Derila vs Other Pillow Options for Back Sleepers
| Pillow Type | Cervical curve support | Height consistency | Head positioning | Notes |
|---|---|---|---|---|
| Derila Ergo | Excellent (contoured groove) | High (memory foam) | Stable central position | Best for back sleepers with neck pain |
| Standard memory foam (flat) | Poor (no neck fill) | High | Moderate | Good pressure relief, no curve support |
| Cervical roll pillow | Good | High | Limited if roll moves | Effective but narrow use case |
| Polyester fill (flat) | Poor | Low (compresses) | Poor | Not recommended for back sleepers with neck pain |
| TEMPUR Neck Pillow | Excellent | Very high | Excellent | 3–5x the price of Derila |
Who Should Use the Derila as a Back Sleeper
- Back sleepers with morning neck pain or stiffness — the most direct use case. The central groove addresses the most common alignment failure in standard pillows.
- People with cervical lordosis issues — those with reduced cervical curve particularly benefit from a pillow that fills the neck from below rather than just supporting the skull.
- Back sleepers who wake with tension headaches — occipital headaches on waking often correlate with poor head positioning overnight.
- Combination sleepers who spend significant time on their back — the symmetrical design means side and back positions are both covered by the same pillow.

Frequently Asked Questions
Is the Derila pillow good for back sleepers?
Yes. The central groove of the Derila contour is specifically designed for back sleepers, filling the cervical curve and keeping the head at neutral height. It outperforms flat memory foam pillows for back sleepers with neck pain.
Is the Derila pillow too high for back sleeping?
The center groove section sits at a moderate loft suitable for most back sleepers. The side sections are higher (designed for side sleepers) — as a back sleeper, keep your head centered in the groove rather than on the raised edges.
Can the Derila help with occipital headaches from back sleeping?
Yes. Occipital headaches on waking often result from sustained pressure on the base of the skull or from the head tilting back during sleep. The Derila’s groove distributes pressure and maintains neutral head position, which can reduce this type of morning headache.
What if I switch between back and side sleeping during the night?
The Derila handles this well — the raised side sections support side sleeping and the central groove supports back sleeping. Position changes during the night don’t require any pillow adjustment.
