Massage Mattress Production, Part 3 — Every Wire and Tube Connected at the Junction Box

XIAMEN, September 2026 — The third installment of the massage mattress production series shows the system connection stage: at the junction box, every black air tube and every colored wire is connected — the point where a mattress becomes one machine.

One Box, Every Connection

Real footage shows a worker connecting multiple black tubes and color-coded wires with terminal ends into a white junction box. Each connection is hand-made and hand-checked, uniting the air system and the electrical system in a single point.

From Flat Layers to a Working Machine

This is the moment a mattress stops being layers of material and becomes a device: air lines meet power lines, all routed through one box, all ready to work together.

The Series Continues

Following the air tube layout stage, this episode keeps showing global buyers exactly how a flat mattress hides an entire massage system — and how it all comes together, step by step.
