High-End Model with Advanced Sleep Technology
SHOPExperience the AiR 4DX Pillow
The AiR 4DX Pillow provides comfortable support that feels as if being held, wrapping around the head and supporting a smooth rollover with a moderate rebound. Nishikawa's AiR 4DX Pillow conditions with high specs, providing a precise fit no matter the sleeping position. Whether on your back or sideways, the advanced version of our AiR 4D Pillow suppresses internal pillow temperature and gives a truly refreshing feeling, integrating the highly breathable structure and the materials used within.
Hybrid 4-Layer Structure Provides Flexibility and Elasticity
Nishikawa's hybrid 4-layer design provides optimal pillow structure with flexibility and elasticity. You can experience sleep technology that combines advanced products and our proprietary cutting-edge design. Using a neck support shape that features two higher sides, your neck is supported gently, reducing the weight on your shoulders. Additionally, our higher-spec materials are featured in the AiR 4DX Pillow for suspension support and restful, cushioning sleep - all night long.
Nishikawa Hybrid Form
The surface layer is made of membrane free foam with high breathability and it disperses the head pressure and reduces stuffiness by structure of supporting with bumps.

Inner Gel Design
The built-in gel design suppresses the internal temperature of the pillow due to a large number of slits running vertically and horizontally throughout the pillow's inner design. AiR 4DX supports comfortable sleep through temperature regulation with its ventilation paths.
Nishikawa Neck Support System
Our special AiR 4DX Pillow structure is based on Nishikawa's Neck Support System*, which comprises a middle concave pillow shape paired with sides that are higher. This keeps the head stable and fits perfectly around the neck, relieving the weight on the curved spine. The high cushioning allows for smooth transition when rolling over with a height that is suitable for sideways sleeping.
*Nishikawa's Neck Support System: In order to support the head and curved spine in a natural posture, we research and develop our pillow to ensure the best position. We seek a comfortable value and propose a mechanizm to select the correct pillow that suits each individual person.

*Inside the fabric, about 3/4 inch and 1/3 inch thick urethane sheets for height adjustment are installed, allowing for adjustment up to a height of 1 1/6 inch in the 3/4 inch unit. We divide the 3/4 cm urethane sheet into four parts, and it is possible to adjust the height separately on the neck, back, and both sides.
The height adjustment is about 3/4 inch thick and is divided into four parts (both sides and the top and bottom of the center), so the height when lying sideways can be adjusted to the individual needs of the sleeper.
