Evidence suggests it may suit

Shoppers deliberately seeking a medium foam-and-coil hybrid.

Readers who want official construction and policy claims separated from attributed outside findings.

Evidence suggests checking first

Comfort and firmness are individual; the brand label is not an independent whole-mattress measurement.

The reviewed sources name 3 components for Signature Hybrid, 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

Analysis

Signature Hybrid: a documented foam-and-coil hybrid with clear identity evidence and important material-detail gaps.

Official sources establish the current Signature Hybrid, its medium marketed feel, approximately 12.25 inches profile, broad construction, and direct-purchase policies. Sleep Foundation publishes an 8.5/10 overall rating for the Signature Hybrid family; findings still vary by firmness and sleeper group. Sleep Foundation publishes 85/100 when normalized from its displayed ten-point scale. It remains that publisher's sleep foundation overall family rating for signature hybrid, not a score created by Nappedia. It is family context, not a score for this exact height or firmness. Exact densities, full fire-barrier composition, supplier changes, and population-level durability are not established, so the record keeps those gaps visible instead of guessing.

Who the cited evidence may support

These are research signals, not a comfort guarantee.

Shoppers deliberately seeking a medium foam-and-coil hybrid.
Readers who want official construction and policy claims separated from attributed outside findings.

What to check before choosing

These limitations may change whether the mattress fits.

Comfort and firmness are individual; the brand label is not an independent whole-mattress measurement.
The complete bill of materials, component suppliers, adhesives, and production-lot changes are not publicly resolved.

Confidence statement

High confidence in current identity and published policy terms; moderate confidence in the public construction outline; no physical test was performed and independent findings remain source- and configuration-scoped.

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.

Forensic Sleep Mechanics • coil deflection

Body Mass Load:

Shoulder: 28mm / Lumbar: 18mm

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.
