The reviewed sources name 3 components for Chill Memory Foam, 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

Chill Memory Foam: a documented cooling all-foam mattress with outside findings kept in their exact source scope.

Official sources establish the current identity, the published medium; independent testing describes medium firm feel, the 10 inches profile, broad construction, and direct-purchase policies to the extent stated. Sleep Foundation publishes a 7.6/10 overall rating for the Chill Memory Foam, while independent firmness testing describes it as medium firm. Sleep Foundation's displayed score is normalized to 76/100 for comparison. It remains that publisher's sleep foundation overall rating for cocoon chill memory foam, 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.

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 “Chill Memory Foam.” Its documented status is Current U.S. mattress research, and the published options are “Medium · 10 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; independent testing describes Medium Firm 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 10 inches. Documented sizes: Queen. ^{1, 2}

What is inside this mattress?

Reviewed sources name Phase-change cooling cover, Memory foam and transition foam, High-density foam base, but one reliable top-to-bottom order was not verified. ^{1, 2}

What did the reviewed sources say about fiberglass or the flame barrier?

Exact SKU recipe not found Disclosure retained at the exact-model or explicitly stated family scope. ^{1, 2}

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

Direct-purchase trial: 100-night direct-purchase trial; eligibility and return 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 a 7.6/10 overall rating for the Chill Memory Foam, while independent firmness testing describes it as medium firm. Sleep Foundation's displayed score is normalized to 76/100 for comparison. It remains that publisher's sleep foundation overall rating for cocoon chill memory foam, not a score created or physically reproduced by Nappedia. Independent exact-model testing and overall rating. The 76/100 normalization is the publisher's exact-model result; the brand's Medium label and independent Medium Firm result are displayed separately. ⁵
