Technical Terminology Explained

Term	Meaning & Significance
Custom	The springs are manufactured to the exact specifications of the sofa company. They are not off-the-shelf, generic parts.
70	This almost certainly refers to the Wire Gauge. In the steel wire world, a higher gauge number means a thinner wire. "70" is an extremely thin and lightweight wire, creating very soft, pliable springs ideal for back cushions, top comfort layers, or very soft-feeling applications.
Steel Wire	Specifies the material. High-carbon steel is standard for its strength, durability, and ability to return to its original shape after repeated compression (memory).
Pocket Spring	Refers to the type of spring: individual hourglass-shaped springs, each encased in its own fabric pocket. These pockets are connected to form a unit. This system provides independent support, minimizes motion transfer, and reduces noise.
Sofa Spring	Clearly defines the application, distinguishing it from mattress springs or automotive springs.
