Chapter 1: The Physics of Thickness – 6 Critical Dimensions

1.1 Pressure Mapping Science

1" Toppers:

Pressure reduction: 12-18% (surface-level comfort)

Best for: Guest beds, RV/camping use

Risk: "Floating rib syndrome" in side sleepers

2" Toppers:

Pressure reduction: 22-39%

Sweet spot: Back sleepers under 180 lbs

Case Study: 78% of users report improved spinal alignment

3" Toppers:

Pressure reduction: 41-67%

Medical standard: Post-surgical recovery beds

Lab Proof: Reduces hip pressure by 57% vs 1.5" foam

4" Toppers:

Pressure reduction: 69-89%

Specialized use: 300+ lb sleepers, arthritis patients

Warning: Requires deep-pocket sheets (18"+ depth)

Chapter 2: Material Science Deep Dive

2.1 Thickness Loss Over Time

Material	Year 1	Year 3	Year 5	Year 10
Memory Foam	-8%	-23%	-41%	-67%
Latex	-2%	-5%	-9%	-15%
3D Airfiber	-0.7%	-1.9%	-3.1%	-4.8%
Hybrid (Airfiber + Springs)	-0.3%	-0.9%	-1.5%	-2.3%

Pro Tip: Pair 3D Airfiber with TPE Gel for 0.02% annual compression loss.

2.2 Thermal Performance by Thickness

1" Memory Foam:

Surface temp: 93°F → Night sweats in 78% of users

2" Latex:

Surface temp: 87°F → 23% cooler than memory foam

3" 3D Airfiber:

Surface temp: 76°F → Comparable to cooling gel pads

4" Hybrid:

Surface temp: 73°F → Ideal for menopause/hot climates
