company news about How does the pocket spring used for sofa?

Of course! That's an excellent question. The pocket spring (often called a "pocketed coil" system) is a modern and highly effective technology used in sofas and mattresses to provide superior comfort and support.

Here’s a detailed breakdown of how it works and why it's used in sofas.

1. What is a Pocket Spring?

A pocket spring unit is made up of hundreds of individual, small steel springs. Each spring is sewn into its own fabric pocket (usually a durable, non-woven polyester). This fabric pocket acts as a sleeve, allowing each spring to work independently from the ones next to it.

This is the key difference from older Bonnell or Helical spring systems, where the springs are all connected together in a single, large web.

2. How It Works in a Sofa: The Core Principle

The principle is Independent Suspension.

• Individual Movement: When you sit on a sofa with pocket springs, only the springs directly under your body compress. The springs around them, which aren't under pressure, remain upright and supportive.

• Targeted Support: This means your weight is supported precisely where it's needed. It also means the sofa is less likely to "roll" you towards another person sitting next to you.

• Contouring: The independent springs allow the sofa seat to contour more closely to the shape of your body, providing better ergonomic support for your spine and hips.

• 3. The Benefits of Using Pocket Springs in a Sofa

  This independent movement translates into several major advantages for the user:

  1. Superior Comfort and Support: Provides a more balanced and body-conforming feel than traditional webbing or tied spring systems. It prevents the "hammock" effect where the whole seat sags under weight.

  2. Reduced Motion Transfer: This is a huge benefit for couples or families. If one person sits down, gets up, or shifts their weight, the other person on the same sofa feels much less movement. The disturbance is contained to a specific zone.

  3. Enhanced Durability: Because the springs work independently, the stress and wear are distributed across many springs rather than concentrated on a few connected ones. This significantly reduces the chance of springs breaking or the entire unit sagging prematurely.

  4. Better Edge Support: Many pocket spring sofas have a reinforced border (often with heavier-gauge springs) around the edge. This prevents the sofa from collapsing when you sit on the edge, making it easier to get up and providing a more stable seating perimeter.
