Do not transfer construction or performance results from another height, firmness, tier, retailer SKU, or production generation.
Public sources do not provide a complete production-lot bill of materials.
The reviewed sources name 3 components for Helix Dawn Elite · Firm · 16", but do not support one reliable top-to-bottom sequence. No cut-open layer stack is shown because that would imply evidence we do not have.

Editorial synthesis
Evidence behind the conclusion
Older 16-inch Helix Dawn; current specifications may not apply.
Helix Dawn Elite · Firm · 16" is listed as retired generation. This page covers the 16-inch profile, Firm (8-9/10 current; 7/10 documented in 2021) feel, and Elite version. It uses the brand documents and independent sources listed below. Results from other heights, options, and generations are not presented as tests of this mattress.
Who the cited evidence may support
These are research signals, not a comfort guarantee.
- Owners trying to identify an older mattress by its exact name, height, and approximate sales period.
- Researchers separating historical reviews from the present-day model.
- Readers checking whether a familiar name represented a different construction generation.
What to check before choosing
These limitations may change whether the mattress fits.
- Nappedia has not slept on, opened, or laboratory-tested this mattress.
- Do not transfer construction or performance results from another height, firmness, tier, retailer SKU, or production generation.
- Public sources do not provide a complete production-lot bill of materials.
High confidence in the researched identity. Confidence is narrower for undisclosed construction, production-lot consistency, and performance claims not tested on this exact configuration.

Landis Capillary Threshold: 32.0 mmHg (4.266 kPa)Interactive Pressure Mapping & Sleep Posture Heatmap
Direct clinical simulation of contact interface pressures, capillary perfusion collapse, and coronal/sagittal spinal curvature across sleeper mass tiers and mattress firmness ratings.
Excessive surface rigidity (9/10) prevents shoulder and trochanter immersion, tilting coronal spine upward and impinging cervical/thoracic nerve roots.
Clinical Perfusion Assessment (Landis 1930): CRITICAL ISCHEMIC HAZARD: Interface pressure at Hips & Pelvis (32.8 mmHg) breaches the 32.0 mmHg (4.266 kPa) Landis capillary closing threshold. Microvascular arteriolar collapse occludes local tissue perfusion, precipitating hypoxic tissue acidosis, sensory paresthesia (numbness), and frequent involuntary nocturnal tossing/turning.
Ischemic hazard detected (32.8 mmHg >= 32.0 mmHg Landis threshold). Capillary circulation occluded.

Method, sample, and source kept attached
Performance evidence matrix
A result describes a particular test method and sample. When reputable reviewers disagree, this file records the disagreement instead of inventing a consensus score.
Zoned Biomechanics (Hooke's Law): Differential wire gauges isolate body mass zones. While plush 16.0 AWG coils allow deep shoulder contouring (28mm), reinforced 14.5 AWG lumbar springs resist pelvic rotation under heavy loads, arresting sag at 30mm to maintain neutral lordotic alignment (Δy ≈ 0).
Simulated Hooke’s law pocket coil deflection across anatomical body load distributions.

Warranty Proration Cliff & Fine Print Analysis
Mattress warranties advertised as "25-Year" or "Lifetime" typically undergo an actuarial transition into a steep proration cliff after Year 10. Consumer defect claims require rigid straight-edge depth proof and strict foundation compliance.
- Years 1-10: 100% Non-Prorated. The manufacturer covers 100% of replacement or repair costs ($0 customer copay).
- Full Tenure: 100% Non-Prorated through Year 10. (No proration tiers).
- Round-Trip Freight Surcharge: Optional repair in Year 3+ incurs a mandatory $149 processing fee.

- 3 Aug 2026 research auditAnalysis
Launch generation. Helix announced six named Elite models and described them as over 15 inches; contemporaneous industry/product coverage records the marketed 16-inch profile. Dawn targeted back and stomach sleepers who prefer firm.
The record was normalized by brand, family, collection, generation, height, firmness, and options before publication.
