Multi-Layer Mattress

The top TPE grid layer features a precision-molded geometric structure with a mesh spacing of 5–30 mm, designed to transform vertical body loads into lateral force dispersion pathways. When compressed, the grid walls deform, redistributing pressure to adjacent mesh cells before it is transmitted to the underlying foam layer. This mechanism effectively mitigates localized stress concentrations-particularly around the shoulders and hips-during sleep cycles lasting 6–10 hours, while enhancing load uniformity across the entire mattress surface.

This structure ingeniously combines the rapid-rebound elasticity of TPE with the slow-response viscoelasticity of foam. The TPE layer instantly returns to its original shape once a load is removed, whereas the foam layer-activated by body heat at 30–35°C-continuously contours to and supports the natural curves of the cervical and lumbar spine. This "dual-speed" response system helps maintain postural stability as the sleeper frequently shifts positions, while also reducing the risk of permanent indentations in the foam layer caused by prolonged compression.

The TPE top layer creates a network of interconnected airflow channels that guide air circulation during the mattress's compression and rebound cycles. When pressure is applied, internal air is expelled; as the mattress rebounds, fresh air is drawn in, thereby establishing a continuous ventilation loop within the mattress interior. Compared to traditional closed-cell foam structures, this design significantly reduces heat accumulation and moisture retention within a typical sleeping environment of 20–35°C.

This multi-layer system achieves a precise division of mechanical functions: the TPE grid handles surface load transmission and dispersion; the foam layer absorbs and dampens residual compressive stresses; and the base layer provides overall structural stability. This "load separation" design concept effectively prevents stress concentration within a single material layer caused by repetitive loading, thereby mitigating the risk of material fatigue failure-specifically addressing issues such as foam collapse or structural deformation that may arise from prolonged daily use in settings such as hotels, residential homes, and recreational vehicles (RVs).
