Technogel is a gel that combines the flexibility to deform like water with excellent stability. It's a material that conforms to the shape and movement of the body, providing comfort and support while allowing for natural movement. It's not just soft; it also has a moderate resilience that prevents excessive sinking, doesn't hinder movement, and distributes pressure appropriately. What is a Technogel Pillow? It's a pillow that utilizes the characteristics of Technogel, which distributes pressure without bottoming out, even when weight is applied. The gel conforms to the body like a custom-made pillow, supporting a good night's sleep. The integrated formation of gel and urethane combines softness and resilience, providing the enveloping feel of a low-resilience pillow and the ease of turning of a high-resilience pillow. It's soft and squishy, yet has a moderate firmness. By combining these two materials, it achieves the smoothness of water and the stability of firm support. Unlike typical low-resilience pillows, Technogel pillows are not affected by temperature and maintain their firmness throughout the year. You can use them comfortably all year round. 99% recovery rate in a durability test simulating 110,000 turns Furthermore, the Technogel pillow has achieved a recovery rate of over 99% in a durability test simulating 110,000 turns. *Tested by the Bogen Quality Evaluation Organization 110,000 turns is equivalent to approximately 10 years of turns.
