System and method for customizing a mattress

The patent applies local quality by varying the density and thickness of foam layers at different locations within the mattress. Specifically, the mattress includes foam layers with different densities arranged in a gradient pattern, where softer foam layers are positioned in areas requiring more cushioning (such as the shoulder and hip regions) and firmer foam layers are positioned in areas requiring more support (such as the lumbar region). This localized variation in material properties enables the mattress to adapt to the natural arcs and curves of the human body while maintaining a relatively simple manufacturing process.

The patent implements local quality by creating zones of varying firmness within the mattress structure. The mattress includes alternating layers of soft and firm foam materials, where the firmness is locally optimized based on the expected weight distribution of the human body. High-weight bearing areas such as the hips and lumbar region are positioned over firmer foam layers that provide enhanced compression resistance, while lower-weight areas are positioned over softer foam layers that provide better contouring. This localized differentiation of material properties allows the mattress to maintain overall structural integrity while providing targeted compression resistance where needed.

The patent applies segmentation by dividing the mattress into multiple distinct foam layers with different density and firmness properties. Rather than using a single uniform foam material, the mattress is segmented into at least two separate foam layers: a softer top layer that conforms to body contours and a firmer bottom layer that provides foundational support. These segmented layers work together to simultaneously achieve contouring support in high-contact areas and uniform support across the entire mattress surface, resolving the contradiction between adaptability and structural stability.
