Negav MattressMZZ4-233B

The Negav Mattress is one of DeRucci’s most recognised and awarded designs, recognised by the Guangdong Province High-Tech Enterprise Association as a Distinguished High-Tech Product in 2020 and consistently ranked as the top-selling single mattress model in China’s premium sleep market. Rated extra firm in feel, the Negav is engineered for sleepers who require precise, high-performance spinal support without softness-related compromise, and has been designed to perform across every age group and body type, from teenagers whose spines are still developing through to older sleepers managing lumbar fatigue and postural strain accumulated over decades. The defining material in the Negav is its proprietary 3D polymer comfort layer, constructed in a hollow X-90° cross-woven structure that delivers an extraordinary 40 support points per square centimetre, amounting to over 1.4 million individual contact points across a standard 180 x 200 cm surface.

This structure operates with six-sided airflow, allowing air and moisture to circulate freely in every direction to maintain a consistently dry, temperature-neutral sleeping environment throughout the night. The 3D material has been subjected to 80,000 compression cycles before production and each completed mattress passes a further 30,000-cycle factory load test equivalent to two adult body weights, ensuring long-term dimensional stability and performance well in excess of industry standards. The material is a pure fibre product free from VOCs and certified to ISO 14001 and OEKO-TEX Standard 100 environmental benchmarks. Beneath the 3D comfort layer, a core of individually pocketed springs in high-carbon, anti-corrosion treated steel provides precise, independent support to every region of the body simultaneously.

Each spring operates in isolation within its own fabric enclosure, responding to movement at the point of contact without transferring pressure to adjacent zones, making the Negav equally well suited to couples with differing body weights and sleep positions. The outer border of the mattress is finished with a breathable grey knit mesh panel that wicks moisture, resists compression, dries quickly and is free from harmful substances, completing a mattress constructed entirely with materials chosen for long-term health, performance and environmental responsibility.
