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 customise 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.


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.

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.



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.

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

The Pascal System means The DUX Bed can be customized to the exact needs of you and your partner. 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 8008 allows the level of lumbar support to be adjusted for each side of the bed by turning the handle at the bed’s base.



With only about 1,000 springs most mattresses may not give you even support across all critical zones of your body. The lack of even support may not only be uncomfortable but can also put additional pressure on your body and spine. Each of the coloured lines to the left represent a different body zone. As you can see, there is not only more pressure against your body but also the distrubution of support is uneven, resulting in long divergent lines. The result is an unsettling night’s sleep.


As is evident by the shorter and more clustered lines, the pressure against the body in a DUX bed with Pascal is not only lower, but the distribution is also more even. With up to 4,188 springs the DUX Bed evenly supports all of the critical areas of your body giving you a more comfortable, deeper night’s rest.
