The reviewed sources name 3 components for Crystal Cove, 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 dossier covers the current U.S. Crystal Cove in Two-sided Medium Soft / Medium Firm · 13 inches. It does not silently merge nearby heights, firmnesses, retailer editions, sibling models, or earlier generations. We have not slept on, opened, or physically tested this mattress.

Editorial synthesis

Evidence behind the conclusion

Analysis

Crystal Cove: a documented two-sided latex and memory-foam hybrid with outside findings kept in their exact source scope.

Official sources establish the current identity, the published medium soft side and medium firm side feel, the 13 inches profile, broad construction, and direct-purchase policies to the extent stated. Sleep Foundation publishes an 8.4/10 overall rating for the Crystal Cove and separates findings by sleep surface. Sleep Foundation's displayed score is normalized to 84/100 for comparison. It remains that publisher's sleep foundation overall rating for crystal cove, not a score created or physically reproduced by Nappedia. Exact component densities and suppliers, Configuration-matched long-term durability, Complete fire-barrier and adhesive recipe remain unresolved, so they are shown as evidence gaps instead of being inferred from a nearby mattress.

Who the cited evidence may support

These are research signals, not a comfort guarantee.

  • Shoppers specifically researching the Crystal Cove rather than a loosely related brand family.
  • Readers who want official product claims separated from attributed independent findings and open questions.

What to check before choosing

These limitations may change whether the mattress fits.

  • Published firmness is a label, not an independent whole-mattress measurement or a comfort guarantee.
  • Materials, suppliers, policies, and construction details can change; the dated sources below define the scope of this page.
Confidence statement

High confidence in the captured identity and cited policy statements; construction confidence follows the disclosure depth shown below. No physical test was performed, and unknown details remain explicitly unresolved.

A result describes a particular test method and sample. When reputable reviewers disagree, this file records the disagreement instead of inventing a consensus score.

Comfort, support, cooling, pain relief, and durability are not universal outcomes or medical conclusions.

The dossier preserves the publisher, test sample, construction, date, and firmness boundary instead of presenting outside work as our own testing.1, 5

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 “Crystal Cove.” Its documented status is Current U.S. mattress research, and the published options are “Two-sided Medium Soft / Medium Firm · 13 inches.” 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 Soft side and Medium Firm side Official current product or lineup wording; not an independent whole-mattress measurement. 1, 2

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

The published profile for this mattress is 13 inches. Documented sizes: Queen. 1, 2

What is inside this mattress?

Reviewed sources name Medium-soft surface, Medium-firm surface, Zoned pocketed-coil core, but one reliable top-to-bottom order was not verified. 1, 2

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

Direct-purchase trial: 365 nights with a required 30-night break-in period; direct-purchase conditions apply Purchase channel, condition, location, pickup, exchange, and final-sale conditions can change eligibility. 3

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

Sleep Foundation publishes an 8.4/10 overall rating for the Crystal Cove and separates findings by sleep surface. Sleep Foundation's displayed score is normalized to 84/100 for comparison. It remains that publisher's sleep foundation overall rating for crystal cove, not a score created or physically reproduced by Nappedia. Independent exact-model testing and overall rating. The 84/100 normalization is exact-product context; surface-specific measurements are not averaged into one universal feel. 5
