Query: “saatva classic plush soft vs luxury firm vs firm coil difference”

Wire Gauge & Comfort Foam ILD Shift

Direct Answer Summary

Saatva Classic achieves its three distinct firmness levels (Plush Soft ~3/10, Luxury Firm ~6.5/10, Firm ~8/10) through two mechanical modifications: micro-pocket coil wire gauge and comfort foam ILD. The Plush Soft utilizes thinner 14.5 AWG micro-coils paired with soft 14 ILD memory foam and softer quilting foams. The Luxury Firm uses balanced 14.5 AWG coils with firmer polyfoam. The Firm utilizes thicker 13.75 AWG pocket coils and high-density 32 ILD foam.

Audited Core Takeaways

  • 1Plush Soft uses 14.5 AWG coils with low-density, compliant 14 ILD contouring foam.
  • 2Luxury Firm uses 14.5 AWG coils with balanced 24 ILD transition foam for universal support.
  • 3Firm uses heavier 13.75 AWG coils and dense 32 ILD support foam for stomach and heavy sleepers.

Spec Verification Protocol3 Actionable Steps

Comparative Spec Verification Protocol

Step-by-step inspection to detect mid-production substitutions and compare component specs.

Select by Primary Posture

Step 1

Side sleepers should choose Plush Soft; back/combination choose Luxury Firm; stomach choose Firm.

Critical Hazard to Avoid

Stomach sleepers on Plush Soft will suffer severe lumbar hyperextension.

Factor Sleeper Weight

Step 2

If sleeper is over 230 lbs, step up one firmness level (Luxury Firm -> Firm).

Critical Hazard to Avoid

Heavy sleepers will bottom out the Plush Soft model onto the Bonnell base coils.

Verify 365-Night Trial Exchange Fee

Step 3

Note that exchanging firmness levels incurs Saatva's standard $99 processing fee.

Critical Hazard to Avoid

Do not guess on firmness without measuring current mattress indentation.
