Risk Probability Analysis

Estimated probability of issues within the first 3 years based on density specs and failure reporting.

Sagging > 1.0 Inch

8% Risk

Low risk due to high-density AirCell™ foam. Primarily seen in foundations with improper slat spacing.

Firmness Drop ≥ 1 Step

35% Risk

Moderate likelihood. Comfort layers naturally break in, resulting in a slightly plusher feel over year 1.

Edge Support Loss ≥ 15%

22% Risk

Dependant on usage. Sitting on the edge regularly accelerates foam fatigue in the perimeter rails.

Cooling Efficiency Decline

5% Risk

Very low risk. GelFlex polymer does not compress like fiber, maintaining airflow channels over time.

Product Definition & Specs

Tracking material specifications across generations to identify potential durability drift.

Core Construction

  • Comfort LayerAirCell™ Memory Foam

Key Metrics

  • Sagging: Vertical depth of unweighted impression.
  • Firmness Drift: Change in ILD or perceived resistance.
  • Cooling Decay: Surface temp return-to-baseline time.
