Editorial synthesis
Evidence behind the conclusion
Medium 11.5 inches Saatva Memory Foam Hybrid; other feels and heights may perform differently.
Saatva 11.5" Memory Foam Hybrid Mattress · Medium is documented as memory-foam hybrid with a medium feel and 11.5 inches profile. The page uses the current or historical documents listed below.

Who the cited evidence may support
These are research signals, not a comfort guarantee.
- People seeking memory-foam contour with a more responsive coil base.
- Shoppers comparing a current direct model with clearly separated QVC or Costco retailer records.
What to check before choosing
These limitations may change whether the mattress fits.
- The order of the AirCradle layer and lumbar crown changed after the 2023 independent test generation.
- A previously published 4 lb/ft³ AirCradle density was not found in the current primary specifications and is treated as unverified.
- Retailer-channel naming does not prove identical or distinct construction.
- Verify the exact Medium / 11.5 inches configuration before relying on family-level findings.
High confidence in the configuration identity and current public dimensions; medium confidence in the published construction; performance confidence depends on whether a source tested this exact configuration.

Manufacturer, retailer, or historical-source wording; not an independent measurement.1, 2Independent or cross-source context
The direct mattress is marketed as Medium around 5-7/10. A retailer alias does not establish a different measured firmness.
Family-level context; transfer to the exact configuration is limited and labeled.6Nappedia interpretation
Treat Medium as a seller label whose real-world feel can vary by body weight, sleep position, production generation, and test method.

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.
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.

Warranty Proration Cliff & Fine Print Analysis
Mattress warranties advertised as "25-Year" or "Lifetime" typically undergo an actuarial transition into a steep proration cliff after Year 10. Consumer defect claims require rigid straight-edge depth proof and strict foundation compliance.
- Years 1-10: 100% Non-Prorated. The manufacturer covers 100% of replacement or repair costs ($0 customer copay).
- Years 11-15: Customer pays 50% of the purchase price ($900.00 on a $1800 mattress).
- Years 16-20: Customer pays 75% of the purchase price ($1350.00 on a $1800 mattress).
- Years 21-25: Customer pays 85% of the purchase price ($1530.00 on a $1800 mattress).
- Round-Trip Freight Surcharge: Optional repair in Year 3+ incurs a mandatory $149 processing fee.
