An Inner Pocket Sprung unit (also known as a Pocket Spring unit) is a core component of a mattress, consisting of hundreds of individual steel springs, each encased in its own fabric pocket. These pocketed springs are then connected together to form a single, cohesive unit. This design is the industry standard for high-quality mattresses due to its superior comfort and support.

• Individual Pocketed Springs:

  Each spring compresses independently, reacting only to the pressure directly above it. This means movement is isolated, so if one person moves or gets out of bed, the disturbance is not transferred across the mattress. The independent action allows the springs to closely contour to the body's shape, providing targeted support to different areas and promoting proper spinal alignment.

• Spring Count:

  This refers to the total number of springs in the mattress. Counts can range from around 500 for a basic model to 2000+ for a luxury model. A higher spring count typically means the springs are smaller and can be packed more densely, allowing for more precise and granular support while reducing the feeling of lying on a spring unit.

• Wire Gauge (Thickness):

  This measures the thickness of the steel wire used in the springs. A lower gauge number means a thicker, firmer wire (e.g., 12-gauge is very firm), while a higher gauge number means a thinner, softer wire (e.g., 18-gauge is softer). Manufacturers use different gauges in different zones of the mattress to provide varying levels of support.

• Spring Height:

  The height of the springs can vary. Taller springs often provide a deeper, more cushioned compression and a plusher feel, while shorter springs can feel firmer.

• Fabric Pockets:

  The material of the pockets is crucial for durability. It's usually a non-woven, spunbond fabric (like polypropylene) that is strong yet flexible enough to allow each spring to move independently without tearing.
