Our newest mattress bed with customisable comfort zones.

DUX 303

DUX 303 is our newest mattress bed with the integrated Pascal system to customize comfort zones. This is our first frameless mattress designed to go into your bed frame. The high level of comfort stems from the interaction between two DUX innovations – the DUX spring system, with thousands of interconnected coils, and our unique Pascal system.

Pascal Customizable Support System

Tailored to Your Needs

The Pascal Customizable Support System allows for customizing your side of the bed. The cassettes come in four variations (soft, medium, firm, and extra firm), personalized in three different zones: shoulders, hips, and legs. All of this is to ensure proper spinal alignment for a good night's sleep.
