Mattress Pocket Springs

## Spring System – Explained in a U-Shaped Way (For Professional Buyers)

### Spring Types (The Core Support Question)
When buyers evaluate a mattress, the real concern is always the same:
**“Will the support be stable, and will complaints stay low?”**

We offer **two spring systems**:
– **Pocket spring (individually wrapped)**
– **Bonnell spring (open coil / round spring)**

Each serves a different market position and price structure.

### Pocket Springs (Where Comfort and Stability Meet)
Pocket springs are chosen for **better motion isolation and body support**.

Key variables include:
– **Steel wire thickness**
– **Spring coil diameter**

These two factors directly control **firmness, durability, and cost**.

### Pocket Spring Count by Mattress Size (What Buyers Really Use)
Spring count is not about marketing numbers—it’s about **matching support to mattress size**.

Typical configurations:
– **Single size**: **200–300 pocket springs**
– **Small Double (120 × 190 cm)**: **400–500 pocket springs**
– **Double size**: **500–600 pocket springs**
– **Queen size**: **700–800 pocket springs**
– **King size**: **900–1000 pocket springs**

These ranges are widely used in export programs because they deliver **consistent support without unnecessary cost**.

### Spring Firmness (Defined by Steel Wire Gauge)
Spring firmness is controlled by **steel wire diameter**, not guesswork.

Common wire gauges:
– **1.2 / 1.5 / 1.8 / 2.0 / 2.2 / 2.4 mm**

Thicker wire means **firmer support and longer lifespan**, suitable for higher-weight users or hospitality projects.

### Bonnell (Round) Springs (When Firmness Comes First)
Bonnell springs are selected when buyers prioritize **firm feel and cost efficiency**.

Common wire gauges:
– **2.0 mm**
– **2.2 mm**

These specifications fall into the **firm to extra-firm category**, making them suitable for **budget-focused or institutional markets** where firmness is preferred.
