Sleep better. Perform better. It's that simple.

We take sleep seriously. We study it. We measure it. We investigate its every aspect. We’re experts in the mechanics of sleep. We understand the vital role sleep plays in the body’s cycle of healing, growing and rejuvenating. DUX High Performance Sleep Systems are the result of over 95 years of research and development. Our component system is designed to provide an unrivaled level of ergonomic support, to help you experience significantly higher quality sleep.


Deep, Rejuvenative Sleep – The Ultimate Goal


In an independent sleep study conducted by the Karolinska Institute of Sweden, the sleep patterns of individuals using a variety of innerspring mattresses were measured using an EEG to record the electrical activity in the cerebral cortex of the brain. The study demonstrated that DUX users not only reached the Deep Sleep stage of sleep faster, but remained there longer. This is especially beneficial since it is during Deep Sleep that the body and immune system recovers and repairs itself.

Deep Sleep is the only sleep stage when the body can repair and regenerate tissue, build bone and muscle, all while strengthening the immune system, which is why we recommend a deep sleep mattress for a quality night of sleep. As you get older, you sleep more lightly and get less deep sleep. Aging is also associated with shorter time spans of sleep, although studies show the amount of sleep needed doesn’t appear to diminish with age. If sleep is cut short, the body doesn’t have time to complete all of the phases needed for muscle repair, memory consolidation and release of hormones regulating growth and appetite. Then we wake up less prepared to concentrate, make decisions, or engage fully in school, work and social activities.



Most people treasure sleep as a time of blessed inactivity. But research shows that sleep is a very active state. We reposition our bodies throughout the night — which is normal and helpful for maintaining good circulation. Our bodies release important hormones during sleep. Our immune systems reboot, and the brain engages in a variety of critical housekeeping functions.

Although we aren’t usually aware of it, we move many times throughout the night when asleep — it’s both normal and healthy. However, if your body sinks low enough into a mattress to suppress movement, your brain will send a signal to awaken so your body can make the required effort to move. This signal is powerful enough to snatch you out of deep sleep. To prevent such an occurrence, it is imperative to have a deep sleep mattress that can dynamically contour to your body movements at night, providing continuous support along its entire length.

The revolutionary DUX sleep science mattress adjusts itself to the weight and shape of your body. It moves as you move. It conforms to your contours, providing active support along every point of your body.
