Concept

nishikawa's AiR Sleep Technology - Design That Changes Your Sleep

nishikawa's AiR Sleep Technology offers a specialized design that can change the way you sleep. The AiR Performance Mattress has a unique bumpy structure that supports using "points" to lead to a high-quality sleep. Combined with the urethane material's elasticity, our design helps you keep a natural sleep posture while evenly distributing the load of your body pressure. With versatility for back-sleepers and side-sleepers, you can roll from one position to another smoothly.

Uncomfortable and restless sleep can have a negative impact on the body, including blocked bloodflow. A comfortable sleeping environment, like sleeping on a cloud, can reduce stiffness and promote more restful, performance enhanced sleep.

AiR is on the cutting-edge of sleep science.

Features

Body pressure dispersion x Sleeping posture retention

The surface of the urethane material with excellent cushioning properties for [AiR] was designed to have bumpy structure so that the mattress fits smoothly to the lines of the body and disperses pressure loads. In addition, the base area firmly catches the body and maintains a natural sleeping posture.

Tossing and turning is made smooth, leading to comfortable sleep.

Comparison of body pressure distribution
Using data compiled by a body pressure distribution measuring instrument, the red parts in the lower back indicate a high level of body pressure while at rest.

A Distinctive Three-Dimensional Cross-Slit Structure Supporting the Trunk of the Body While Asleep
The AiR SI Mattress is designed with a distinctive three-dimensional cross-slit structure that supports individual daily self-maintenance. It realizes a comfortable sleep environment regardless of whether sleeping on one's side or back, providing a balanced support a sleeper needs to wake feeling invigorated after a restful night's rest.
02
Supported by points
About 1900 points on the surface support the body and reduce pressure by not obstructing blood circulation. The base area adjusts the body's sinkage for comfortable sleep.
03
More advanced cushioning
Each block of bumpy structure with 3 x 3 points independently hold the body. It conforms more firmly to the body line and disperses body pressure, allowing smooth turnover and also suitable for side sleeping.
04
Higher breathability
Vertical and horizontal-crossed slits that promote ventilation of urethane foam quickly dissipate moisture such as humidity and perspiration. With less worries pertaining to drying and dust, it is much easier to care for.
