1. Structural design: from overall rigidity to independent response Compression spring adopts a manufacturing process of continuous winding of a single steel wire, and all springs are connected in series through spiral iron wire to form a rigid mesh system (such as Bonnier spring). This integrated design makes adjacent springs highly coupled – when one place is under […]

When we sink into a soft mattress for a night’s sleep, few people realize that what really supports this comfort and health are countless precision-designed and high-performance spring steel wires. They are the invisible skeleton of the mattress, and the difference in their parameters is enough to subvert the quality of sleep and the durability of […]

1. Material: Double game between luxury and practicality The core value of leather sofas comes from the leather grade: First-layer cowhide (especially yellow cowhide) retains natural pores and has excellent breathability. The surface temperature in summer is 2-3℃ lower than that of fabric, but the cost accounts for 35%-40% of the total product price; Second-layer leather has […]

1. Cleaning tools: accurate selection, twice the result with half the effort The choice of cleaning tools and dosage forms is directly related to the life and effect of leather. For daily floating dust, dry wiping with a microfiber cloth is the first choice to avoid friction damage with ordinary rags (the International Leather Crafts […]
