Bottom line
Baby side: Extra Firm 6 inches Saatva Crib Mattress; other feels and heights may perform differently.
What the research suggests
- Reported
- Results vary
- Not enough public information
Mattress surface, not a sleeper position. Infant and toddler surface labels are not adult sleep-position recommendations.
Adult body-weight fit ranges do not apply to a crib mattress.
The reviewed sources do not provide a clear cooling finding for this mattress.
The reviewed sources do not provide a clear motion isolation finding for this mattress.
Extra-firm infant support surface. Creates the firmer infant-facing side identified by Saatva.
A label is not an independent whole-mattress measurement.
Skip if: Prefer deep contouring memory foam hug with zero motion transfer?
Caregivers verifying exact 28-by-52-inch crib fit and the correct infant or toddler side.
The baby and toddler surfaces belong to one flippable mattress, not two separately sold mattresses.
This research is not pediatric or safe-sleep medical advice; caregivers must follow the crib maker and current CPSC/AAP/pediatric guidance.
Saatva's current pages conflict on the exact flame-barrier material.

This page covers the exact database record “Crib Mattress · Baby side: Extra Firm · 6".” This record tracks one side of a dual-sided mattress, not a separate purchasable mattress. Family-level evidence is used only where the public sources describe a shared construction; exact-configuration evidence is labeled separately. Nappedia has not slept on, opened, or laboratory-tested this mattress.
Editorial synthesis
Evidence behind the conclusion
Baby side: Extra Firm 6 inches Saatva Crib Mattress; other feels and heights may perform differently.
Crib Mattress · Baby side: Extra Firm · 6" is documented as dual-sided crib mattress with a baby side: extra firm feel and 6 inches profile. The page uses the current or historical documents listed below. Independent findings appear only when the tested version is identified; missing results are marked as unknown.
Who the cited evidence may support
These are research signals, not a comfort guarantee.
- Caregivers verifying exact 28-by-52-inch crib fit and the correct infant or toddler side.
What to check before choosing
These limitations may change whether the mattress fits.
- The baby and toddler surfaces belong to one flippable mattress, not two separately sold mattresses.
- This research is not pediatric or safe-sleep medical advice; caregivers must follow the crib maker and current CPSC/AAP/pediatric guidance.
- Saatva's current pages conflict on the exact flame-barrier material.
- Verify the exact Baby side: Extra Firm / 6 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
Saatva labels the baby side Extra Firm and the toddler side Firm. Sleep Foundation's roundup used evaluator-scale firm 7 and medium-firm 6; keep both scales attributed.
Family-level context; transfer to the exact configuration is limited and labeled.6Nappedia interpretation
Treat Baby side: Extra Firm 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.
