The DUX® 101 dynamic two layer spring construction is the perfect introduction to the legendary DUX comfort and support. 

The DUX 101 combines our company’s proud heritage with advanced technology in its purest form - a true statement and signature of DUX know-how, craftsmanship, and our ability to create high quality and long-lasting products.

The mattress is based on the original DUX 1001 in features yet is built without our signature internal hardwood frame.

THE DUX 101 Frameless Features



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.

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.
