Performance of Home Furnishing Sponge Fillings

The performance of home furnishing sponge filling is primarily reflected in aspects such as resilience, support, durability, breathability, eco-friendliness, and comfort.

Resilience and Support
High-density foam (e.g., with a density ≥ 40 kg/m³) possesses excellent resilience and supportive properties; it effectively distributes pressure and prevents sagging or deformation resulting from prolonged sitting.

Durability
High-quality foam demonstrates a hardness loss of less than 15% after undergoing 80,000 fatigue cycles (well within the national standard limit of 32%), offering a theoretical service life of over 10 years.

Environmental Friendliness and Safety
High-end products utilize a manufacturing process free of adhesives, heavy metals, and mineral fillers, resulting in Total Volatile Organic Compound (TVOC) emissions significantly lower than national standards.

Comfort
Medium-density foam delivers a "just-right" sitting sensation-neither excessively soft (causing excessive sinking) nor overly rigid. Certain products further optimize the initial sitting experience through advanced micro-structural design.
