Editorial reconstruction of a cut-open mattress representing latex-hybrid construction for WinkBed · Plus · 13.5" — **Research-based reconstruction:** The cut-open image represents the documented latex-hybrid construction and the adjacent list follows the cited public construction record. The illustration does not claim an unpublished thickness or exact visual proportion. Layer thicknesses, colors, and visual proportions are schematic. Localized lumbar components are not separately visible. This is not a teardown or physical inspection by Nappedia.

Analysis

Plus / firm heavy-duty option 13.5-inch Brand-direct catalog; options may change the materials.

WinkBed · Plus · 13.5" is listed as current brand-direct. This page covers the 13.5-inch profile, Plus / firm heavy-duty option feel, and Brand-direct catalog 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.

Readers researching the exact 13.5-inch configuration rather than the family name alone.
Shoppers comparing the published Plus / firm heavy-duty option feel within the The WinkBed lineup.
Researchers who want source dates, purchase-channel warnings, and unresolved material details visible before visiting the merchant.

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.

Confidence statement

High confidence in the researched identity. Confidence is narrower for undisclosed construction, production-lot consistency, and performance claims not tested on this exact configuration.

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.

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.
