Why customers love the Pure+ mattress

Pure+ – The mattress
with extra functionality

The Pure+ mattress is our premium mattress with two functional layers that can effectively contribute to sleep optimisation.

With its modular layers, this SEVEN SUNDAYS revolutionary mattress system ensures an optimum lying sensation. Depending on the model, different layers are available. With the Pure+, you get two functional layers with different benefits and a base layer. Because the layers are not glued together, you can easily alter the arrangement of the functional layers to change your lying sensation - whenever you like.

The SEVEN SUNDAYS for the most demanding sleeper: Designed to be particularly ergonomic and back-friendly.

With our advanced 5-zone layer, the Pure+ contains a layer with optimised zoning that ensures especially ergonomic and back-friendly support. This is different from the Pure, where the zoning is realised by incisions in the base layer. Thanks to the 5-zone layer, the mattress can adapt even better to your body for even more selective pressure relief. It makes a functional contribution to a healthy sleeping position with a high level of sleeping comfort.

Layer 1 of the Pure+ 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 lying sensation.

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, with 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 memory mattress with a top level of comfort. 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 feeling 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 the 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 vacuum to ensure 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 through 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 rusty in the morning.

Softness layer

Sleep enveloped in cloud-like softness – as if you’re 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 layer. 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 Pure+ 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.

The mattress is divided into different areas, so-called zones, with different levels of firmness in the right areas. This is very beneficial from an ergonomic point of view for healthy positioning of the body, spine and joints, especially for side and back sleepers, as it 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 in the neck.

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

For a 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 Pure+ mattress:
The base layer

The 3rd layer of the Pure+ is our high-quality base layer, which we have designed to complement functional layers in the best possible way.

Unlike our functional layers with their special ergonomic and comfort features, the base layer is not designed to provide a specific lying sensation or health benefit. During development, it was important to us to have a layer that was as neutral as possible in terms of a lying sensation, that improved general sleeping comfort and that ensured that the respective properties of the functional layers above it were ideally enhanced.

The base layer consists of an innovative hybrid foam where nature meets technology.

For the best possible sleep quality, we use a further development of conventional cold foam for the base layer, in which cutting-edge polymers are combined with natural latex. Thanks to its excellent elasticity and comfort properties, the base layer provides optimum support for the body and back and enables the spine to be positioned correctly. The natural latex content makes it particularly point-elastic and soothingly soft. The water-based material is very hygienic, hypoallergenic, dimensionally stable, durable and also 100% green and recyclable. A patented treatment of the cell structure also optimises air circulation to remove body moisture for a pleasant sleeping climate. The best basis for your mattress designed to last a lifetime.
