1.8mm High Carbon Steel Sofa Pocket Spring 4-7 Turns

Spring Count: The total number of springs in the unit. For a 3-seater sofa, counts can range from 300 (economy)

to 1000+ (premium).

Spring Height: Typically ranges from 50mm (2") to 100mm (4") for sofas. Taller springs often provide more "push"

 and a deeper, plusher feel.

Wire Gauge: The thickness of the steel wire. A lower gauge number means a thicker, firmer spring (e.g.,

13-gauge). A higher gauge number means a thinner, softer spring (e.g., 18-gauge). Common range is 13- to 18

-gauge.

Pocket Fabric: The material of the encasement. Non-woven polypropylene is standard. Higher-end options

 use spunbond or other advanced materials for better breathability and durability.
