The reviewed sources name 3 components for Hybrid Latex Mattress, 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.

Scope before conclusions

This file covers Hybrid Latex Mattress at the identity and configuration boundary stated above. The two imported firmness rows consolidate because the manufacturer explicitly publishes the same 11-inch design, three-inch latex thickness, materials, and coil architecture for both; the ILD and independent firmness results remain configuration-specific. We have not slept on, opened, or physically tested this mattress.

Editorial synthesis

Evidence behind the conclusion

Analysis

Hybrid Latex Mattress: one current hybrid family with two selectable latex ILDs.

Official sources establish the marketed name, 11 inches profile, medium or medium-firm feel context, and the construction disclosed below. Sleep Foundation tests both firmnesses, displays a family overall rating of 8.8/10, and separates sleeper-fit results by Medium and Medium Firm. Sleep Foundation's displayed overall result is normalized to 88/100. It remains that publisher's sleep foundation eco terra family overall rating, not a Nappedia score. Unknown details remain visible rather than being filled with sibling-model claims.

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).

Questions found during research

Common questions, answered from the evidence

These themes recur across brand help centers and independent review research: model name, firmness, sizing, construction, base compatibility, materials, and purchase terms. They are not presented as search-volume rankings.

Which exact mattress does this page cover?

This page covers “Hybrid Latex Mattress.” Its documented status is Current U.S. family record, and the published options are “11 inches · Medium (ILD 24-26) or Medium-Firm (ILD 29-31).” Findings from another height, firmness, retailer version, or generation are not automatically treated as equivalent. ^{1, 2}

What firmness is documented for this mattress?

Medium or Medium-Firm Official label and/or explicitly attributed independent firmness result; labels are not universal outcomes. ^{1, 5}

How tall is this mattress, and which sizes were documented?

The published profile for this mattress is 11 inches. Documented sizes: Published availability. ^{1, 2}

What is inside this mattress?

Reviewed sources name Organic cotton and wool surface, Latex comfort layer, Fabric-encased coil core, but one reliable top-to-bottom order was not verified. ^{1, 2}

What trial, return, or exchange terms apply to this mattress?

Trial and returns: 90 nights; a 30-night adjustment period applies, and early return or concierge-removal fees can apply Final-sale, minimum-use, fee, location, condition, and purchase-channel rules can apply. ³

What independent evidence is available, and which configuration did it test?

Sleep Foundation tests both firmnesses, displays a family overall rating of 8.8/10, and separates sleeper-fit results by Medium and Medium Firm. Sleep Foundation's displayed overall result is normalized to 88/100. It remains that publisher's sleep foundation eco terra family overall rating, not a Nappedia score. The 88/100 normalization is Sleep Foundation's family score. Firmness-specific observations remain attached to the tested firmness and are not our measurements. ⁵

Configuration-specific long-term failure rate: Not established The reviewed source set does not support a more specific exact-current claim.
