Layer 1 of the Box Spring Mattress:
Your functional layer choice

You can choose the layer that best meets your requirements from three high-quality layers which have different properties.

With SEVEN SUNDAYS, not only can you optimise your sleep, you can also decide for yourself how you want to lie. Choose between the cuddly Memory layer made of high-performance Visco foam with a pronounced memory effect, the springy Latex layer made of 100% natural latex with perfect adaptability, and the Softness layer with super fluffy down for an extra soft feel.

Softness-Layer
Memory-Layer

Rest - with a feeling of weightlessness

The Memory layer is the most chosen functional layer, as lying on memory foam is very popular. Our high-quality organic Visco foam with organic Aloe vera oil and its high density of RG 55 guarantees the ideal memory effect at the highest level in ergonomic and ecological terms, offering both reliability and, above all, sustainability. Just the right thing if you want to sleep on a top comfort level memory mattress. Because not all Visco foam is the same. With its special thermoelastic properties, the Memory layer ensures precise body adaptation with the relieving effect of pressure distribution - ideal even for pressure-sensitive people. Its orthopaedic properties are very beneficial in cases of tension, spinal problems or circulatory disorders. The memory foam reacts to your body temperature, offering a rather soft, but extremely pleasant stable feel due to its viscosity – a feeling similar to weightlessness. Because the breathable foam moulds to your body and holds it in place, the layer is perfect if you move around a lot in your sleep, as it helps your body rest more comfortably. Let the Memory layer carry you to sleep and experience a new dimension of relaxed lying.

Latex-Layer

Keep moving – and lie in an ultra-comfortable position

The Latex layer is a valuable component of our modular mattress system. Latex is known for extremely high sleeping comfort but is not usually used in inexpensive mattresses for the mass market due to its price. This is certainly not the case with SEVEN SUNDAYS quality products. We use 100% natural latex made from chemical-free natural rubber with a super high density of RG 85. Our sophisticated Talalay foaming method uses a vacuum to ensure a uniform density and thus a constantly comfortable feeling from head to toe. Compared to synthetic latex, natural latex is more breathable, more adaptable and, of course, more environmentally friendly. In addition, the organic material is dimensionally stable and durable beyond comparison. While memory foam only becomes supple with your body heat, latex reacts to your weight and body shape. The comfortable pressure relief it gives is very pleasant in case of pain. When the pressure on the layer decreases due to a change in sleeping position, the material immediately springs back into its original shape. This property promotes natural sleep movement and is ideal if you often feel stiff in the morning.

Softness-Layer

Sleep enveloped in cloud-like softness – just like in a 5-star hotel

The Softness layer is the wellness sleeping solution from SEVEN SUNDAYS that will make you feel as if you’re in a luxury hotel. The layer consists of a specially developed material mix of 40% gently cleaned duck down feathers (no live plucking) with a high fill power and 60% natural shredded latex. Feathers and latex are incorporated in the layer in the perfect ratio and in proven quantities to create a cosy body feeling. The multi-chamber system with comfortable quilting ensures that the down and natural shredded rubber remain evenly distributed in the mattress. Of course, the Softness layer does not have the pressure-relieving and supporting properties of the Memory or Latex layers. But if you are looking for cuddly soft sleeping comfort from your mattress, this functional layer is perfect. Because it is not only incredibly soft. The combination of quality down with high-quality natural shredded latex, which reacts precisely to the contours of your body, makes it much more supportive than simple down toppers. Another advantage is the climate-regulating properties, which have a warming or cooling effect depending on the temperature – for a comfortable sleeping climate all year round.

Layer 2 of the Box Spring Mattress:
The 5-zone layer

The 5-zone layer is a functional layer with five highly optimised lying zones for particularly ergonomic support of the spine.

For healthy positioning of the body, spine and joints, it is highly beneficial from an ergonomic point of view, especially for side and back sleepers, if the mattress is divided into different areas, so-called zones, with different levels of firmness in the right places. This provides extra cushioning to heavier or more pronounced body regions. The most crucial area is the shoulders, where a lot of pressure can occur when lying down. The mattress should be softer there and yield more to prevent pain. The same applies to the pelvic area. The head zone, on the other hand, should have a stabilising effect to prevent the spine from bending at the neck.

Benefit from optimised zoning with the 5-zone layer for a noticeably more relaxed sleeping experience.

To offer really body-friendly support or relief, we have designed a real continuous zoning instead of the mirrored mattress zones common in many normal 5- or 7-zone mattresses. Furthermore, we do not simply rely on cutting and milling, but on a combination of different cold foams for high point elasticity. In the head, cervical, chest and leg zones, firm cold foams are used for increased support. In the shoulder zone, there is a very soft cold foam to better absorb pressure and maintain the correct posture when lying. The pelvic zone is medium firm to provide extra cushioning to the hips and pelvis, but without letting them sink into the mattress. Our optimised zoning makes a noticeable contribution to the prevention of back problems.

Layer 3 of the Box Spring Mattress:
The Stretch layer

Do you often have back problems? Are you looking for a mattress that provides relief? Then sleep on the Stretch layer.

Back pain is one of the most common ailments. The right mattress can go a long way towards relieving the discomfort, allowing your body to recover overnight and your muscles to relax rather than tense up. It is important to have high point elasticity, reliable support, optimum body adaptation and optimised lying zones. But we at SEVEN SUNDAYS wondered whether the perfect mattress for back pain should be able to do even more. This is how our most effective, popular Stretch layer came into being.

Now you can do something for your back and spine every night - simply while sleeping.

The Stretch layer is a unique functional layer from the SEVEN SUNDAYS Research and Development Department, which we created together with qualified orthopaedists and physiotherapists. It consists of a high-quality and dimensionally stable cold foam with a special inverse lamellar structure. Derived from the Dorn Method for gentle repositioning of the vertebrae, the lamellae gently pull your vertebrae apart when you lie down. This stimulates the regeneration of the intervertebral discs and promotes their nutrient supply. By lying on the Stretch layer, you can now actively improve your back health. The Stretch layer is available exclusively in the Classic and Box Spring Mattress.
