The Science of Cushion Resilience
Sofa sagging and cushion collapse are the #1 reason for guest complaints in hotels. Foshan Demi Furniture enforces a strict Zero Recycled Scrap Foam policy, utilizing exclusively virgin high-density polyurethane sponge.
Foam Density vs. Life Expectancy
- Standard Retail Foam (20D–25D): Degrades and collapses within 6–12 months of daily use.
- Commercial Medium Density (30D–35D): 3–5 year operational lifespan with <8% compression loss.
- Demi Contract Grade (38D–45D): 7–10 year lifespan; retains 92%+ of original height after 50,000 dynamic impact cycles.
Sandwich Cushion Construction
To balance sink-in cloud comfort with robust spinal support, our cushions utilize a 3-layer progressive sandwich:
- Base Core: 45D ultra-high-resilience foam providing foundational support.
- Transition Layer: 35D elastic comfort foam absorbing body contours.
- Crown Wrap: 300g/m² OEKO-TEX certified fiber fill or natural down feathers for tactile softness.
