Spring Count and Layout:

The number of springs and their arrangement (e.g., 6x4, 8x5, 10x6). More springs generally mean finer support and a firmer feel.

Example: A unit that is 60cm x 60cm with 6x6 springs uses 36 springs, each about 10cm in diameter.

Spring Specification:

Wire Tensile Strength: Premium units use high-carbon steel with 1900MPa - 2200MPa.

Wire Diameter: Thicker wire (e.g., 2.0mm, 2.2mm, 2.3mm) creates a firmer unit.

Coil Count: The number of turns in each spring (typically 4.5 to 5.5 turns). More turns can offer a more progressive feel.
