THE DUX 3003 Features



 Comprised of interchangeable cassettes of different spring tensions, our patented Pascal System lets you custom configure its parts to match the exact requirements of your individual body shape and weight - and to change them when you change.



The leg support cassette is designed to slightly elevate your legs to help align your spine and maintain circulation to your feet. 



The hip support cassette allows your hips to sink in while providing just enough counter support to help keep your spine straight, loose and relaxed.



The shoulder support cassette is designed to let your shoulders sink in to reduce pressure points that can inhibit circulation.



Remove the top pad and unzip the top of the bed. 

A zipper allows for easy access to the Pascal spring cassettes.

The Pascal spring cassettes come in three densities: soft, medium and firm.

Customize the support and comfort for each side of the bed.



Every DUX bed comes with our Xupport Top Pad. This 2.5 inch replaceable cotton covered latex top pad adds extra softness and cushioning, and is an integral part of The DUX® Bed, enhancing the personal feel and comfort vital to a great night’s rest. Unlike most beds with pillow tops, our top pad is not fastened to the bed. Not only does this complement the contouring nature of our beds, but in the case of a spill or wear, you can simply replace the top pad without having to replace your entire mattress.

Dynamic Support 


Only the dynamic nature of a spring system can contour to all of your movements at night. The revolutionary DUX spring system adjusts itself to the weight and shape of your body. It moves as you move. It conforms to your contours, providing continuous, dynamic support along every point of your body. 

The DUX spring design is neither too firm nor too soft. It is flexible enough to let your shoulders and hips sink in, yet resilient enough to rise up and support your lower back. Vital pressure points — especially your spine — are supported in the most ergonomically healthy positions possible, letting your blood circulate freely while your muscles completely relax.

DUX, from the Bottom, Up:  


Our bottom layer of springs provides deep suspension. This section absorbs and distributes weight so the bed remains stable when you or your partner move about. 


The middle spring layer delivers continuous lumbar support while rising up to conform to the contours of your body.


The penultimate layer of a DUX bed is comprised of our customizable Pascal Cassettes. Each cassette is selected to correspond to your individual needs.


Our plush Top Pad forms the upper-most layer of a DUX bed. Utilizing latex harvested from the Hevea rubber trees, and cased in pure, long-fiber cotton.

Internal Frame Mattress

The DUX Bed is not just another mattress– it's a piece of furniture built to last for generations. With The DUX Bed, you no longer need a bed frame because the hardwood frame is literally built into the beds foundation. Simply thread the leg of your choice into place on the interior frame. Get tired of your leg selection– simply replace the leg to fit your needs.

Oeko-Tex® Standard 100 Certified

We are a proud recipient of the Oeko-Tex 100 Certificate. The Oeko-Tex Standard 100 is an independent testing and certification system for textile raw materials, intermediate and end products at all stages of production. In The DUX Bed you can be sure you are sleeping on a bed that meets strict human-ecological requirements of being completely free of any unhealthy or harmful chemicals.



The DUX Bed is comprised of customizable components. Our top pad is not fastened to the bed, the top of the mattress unzips to allow access to the Pascal® customizable cassette system and the dual spring bases operate independently of each other. 

Components are replaceable, and some even upgradable. The result is a bed that can not only be restored as it shows wear, but may be improved with the release of new accessories and technological innovations.




DUX is more than just a bed – it’s a vehicle for wellbeing. It’s the culmination of 90 years of research and innovation. The ultimate purpose of the DUX System is to enable deep sleep. This sleep stage is the most important and the most elusive. Researchers at The Karolinska Institute – the prestigious medical university that awards the Nobel Prize in Physiology and Medicine – performed a study investigating the effect different types of mattresses had on the body and sleep quality. Their results showed that those who slept on a DUX bed not only fall asleep faster, but remained in deep sleep longer - approximately one hour more each night. This benefit is extremely important to your health since it is during Deep Sleep that the body and immune system can repair, rebuild and restore itself.
