DUX Interchangeable Cassette

Pascal®: Our Customizable Cassette System

Unless you and your partner are identical in shape, size and weight, you need a bed that will take your inherent differences into account. Our Pascal system of interchangeable spring cassettes allows you and your partner to individually customize your side of the bed for optimal bed support and comfort. In a DUX bed, your personal comfort no longer has to be a compromise.

Interchangeable Cassettes

The top layer of The DUX Bed with Pascal can be unzipped to reveal six interchangeable spring cassettes; three for each side. The cassettes come in three different tensions, soft, medium and firm. Simply open the top of the bed and arrange the cassettes based on your body size, shape and needs.  While you may need firmer bed support under your lower back, your partner may need more flexibility in order to achieve proper spinal alignment.

Those Ingenious Pascal Springs

The springs in the Pascal cassette system represent the type of triumph sleep engineers dream about. The design of the springs, and the specific type of steel used to make them, is the fruit of years of research and testing. Each spring is a mechanical wonder, manufactured to exacting specifications for optimal mattress support. Every spring is calibrated to provide a precise degree of lift to counteract a predetermined level of weight.

Pascal: The Man And The Measure

We named our patented Cassette System in honor of the famed French physicist and mathematician Blaise Pascal. A “pascal” is an international unit of measure for pressure — in our case, a measure of the precise pressure required by each spring in our family of cassettes to support a resting body of a particular size, shape and weight.

Every Body is Unique

With the Pascal System, The DUX Bed can be customized to the exact needs of you and your partner so each side of the mattress supports your individual body type throughout the night. The cassettes are designed to fit body types and body parts — they not only accommodate differences in weight and height, but in shoulder width, hip density and musculature. 

Additionally, the DUX 818 allows the level of lumbar support to be adjusted for each side of the bed by turning the handle at the bed’s base.
