Kenko™ Sleep Technology



The Kenko Sleep System is scientifically designed to increase relaxation and support a variety of physical and mental functions for restful and restorative sleep.

The Sleep System combines a Nikken Kenko Naturest® Mattress Topper with a Kenko™ Comforter and Kenko Naturest® Custom Pillow. Each component contains advanced technology designed to improve sleep quality.


The Kenko Naturest® Mattress Topper features a design that has no springs. Its construction shapes itself to body contours. This prevents the formation of pressure points that can interrupt sleep or prevent the sleeper from attaining optimal rest. The latex foundation is firm yet comfortable, and resists sagging.This support system is designed to accommodate all body types.

Magnetic components

RAM™ (radial-axis magnetism) or SpyderRAM™ Technology in the Kenko Naturest® Mattress Topper and SpyderRAM in the Kenko Naturest® Custom Pillow feature spherical magnets which produce a series of overlapping magnetic fields.

This magnetic technology produces a cocoon of magnetism that envelops the sleeper.

Massage surface

A massage layer is directly beneath the Mattress Topper cover. This layer is a surface of nodules that impart a passive massage effect. It uses the sleeper’s own motion to create a gentle stimulation and help to ease tension.

Built-in ventilation

Air-flow ventilation within the various components promotes the free flow of air without creating drafts. Latex foam and fabric breathability insulate but do not trap air in hot spots.

Far-Infrared Technology

Nikken Far-Infrared Technology absorbs energy from a variety of sources — sunlight, body or room temperature — and releases it as energy in the far-infrared part of the spectrum. Energy-reactive fibers constantly receive intake energy and reflect it as gentle warmth. In warmer weather, these fibers reach a limit in the amount of energy absorbed, and the excess heat will pass through the material and escape.

Ionic Comfort Technology

Ionic Comfort Technology is the name of a subsystem within Sleep System components that generates negative ions. These odorless, invisible, charged particles, identical to those found in the air in forests and near waterfalls, are emitted by fibers in the comforter and pillow and assist in imparting a sense of relaxation.

Advanced pillow design

The Kenko Naturest® Custom Pillow has a special filler of shredded latex. It is designed for the user to subtract or replace filler to achieve the desired degree of firmness. The latex is especially resilient, to resist being compressed flat. A special insert provides head and neck support for proper spinal alignment.

A sleep mask is available which provides light-blocking cover for eyes and includes magnetic and far-infrared components.


A sleep system that offers improved support for the musculoskeletal system, improved temperature control and additional enhancements in comfort will contribute to quality sleep.

This is significant because according to many medical authorities, quality sleep may be the single most important factor in maintaining long-term health.

Regular sleep on a Kenko Sleep System can contribute to better mental function such as improved learning ability and decision-making faculty, improved memory, greater alertness and increased mental performance.

Quality sleep can also support physical health including resistance to/recovery from fatigue, improved immune system function, better ability to resist premature aging, increased ability to resist stress, and better-regulated hormone production that can help prevent weight gain or obesity.
