1. Seasonal Material Matching

Spring/Summer Essentials:

• Tencel (Lyocell): Absorbs moisture 50% faster than cotton, with natural breathability. Blend with 30% linen for enhanced airflow.
• Lightweight Cotton: Opt for 60s thread count with percale weave to prevent heat retention.
  Autumn/Winter Must-Haves:
• 120s Long-Staple Cotton: 500 threads per square inch create thermal-insulating layers. Brushed finishes add warmth.
• Supima Cotton (38mm+ fibers): Reduces friction during sleep, ideal for sensitive skin.
  Curtain Light Control:
• Bedrooms: Level I Blackout (99-100%) using triple-woven fabric + UV-blocking coating.
• Living Rooms: Level III Semi-Sheer (70-80%) linen for soft daylight diffusion.

2. Craftsmanship & Sleep Health

Thread Count Decoded:

• 60s Cotton: Best for daily use (balanced durability and cost).
• 120s Sateen: Requires delicate cold-water washing to preserve silky texture.
  Pillow Height Formula:
• Back Sleepers: 8-10cm height (match fist thickness).
• Side Sleepers: 12-14cm + 0.5cm compression buffer for memory foam.
  Down Duvet Calculations:
• Fill Power (FP): FP 600+ = -5°C comfort.
• Fill Weight Formula:
  Fill Weight (g) = (22 - Desired Temp°C) × (Height in cm)² / 1000
  Example: 170cm adult needs 1200g of 95% FP700 goose down for 10°C nights.

3. Safety Standards Demystified

OEKO-TEX® CLASS I:

• Tests 112 chemicals (e.g., formaldehyde <20ppm, lead <0.2mg/kg).
• Mandatory for baby products via saliva-resistance tests.
  Down Labeling Standards:
• US IDFB: Requires “down cluster %” – 85% clusters outperform 90% generic “down content.”
• EU Standard: 90% clusters + traceable origin certification.
  Colorfastness Ratings:
• AATCC Grade 4+: Withstands 50+ machine washes (use enzyme-free detergent).
• Industrial Testing: 48-hour UV exposure + 40°C water immersion.
