Why customers love the Pure mattress

Pure – The perfect introduction into the world of regenerative sleep

The Pure mattress is our “entry level” model and provides you with attractively priced access to our E3 sleep technology for relaxation, recuperation and energisation.

Like all modular SEVEN SUNDAYS mattresses, this affordable premium mattress has three unbonded individual layers. It consists of a functional layer and two high-quality base layers. You can choose the functional layer yourself according to your personal sleeping needs, so that you lie the way you expect to lie on your dream mattress.

The SEVEN SUNDAYS mattress for everyone: Developed for regenerative sleep – without compromise.

The Pure mattress is made to be comfortable as well as ergonomic and back-friendly. The two base layers are designed in such a way that they enhance both the ergonomics and the feeling of full relaxation of the functional layer. It offers you everything a high-quality mattress should offer. The quality is so high that you can even do without an expensive slatted bed frame underneath. And if you want to enhance your sleeping experience even further with our functional sleep architecture, you can always equip the mattress with additional functional layers.

Layer 1 of the Pure mattress:
your functional layer choice

Depending on how you prefer to lie on your personal Pure, you can choose from three highly effective functional layers - Memory layer, Latex layer or Softness layer.

Both the Memory layer and the Latex layer guarantee perfect point elasticity and pressure relief for orthopaedically sound sleep – no matter how tall or heavy you are. Both are also recommended for allergy sufferers. The decisive factor is to choose the layer that suits you best. The Softness layer is above all a comfort layer for all those who dream of a cosy, soft feeling of wellness.

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 & 3 of the Pure mattress:
The base layer

As the 2nd and 3rd layer, the Pure contains our base layer, which is designed for high sleeping comfort for all needs.

The base layer is a comfortable layer made of a special cold foam made of natural latex and the latest polymers. A perfect combination of nature and technology provides the necessary basis to bring out the full ergonomics and comfort features of your functional layer. The high-quality and durable material is characterised by optimal pressure distribution and effective air and moisture regulation, thanks to an open cell structure. It stays supple and elastic. The base layer is by no means less high-quality than the functional layers integrated in the more high-end Pure+ and Classic models. The functional layers simply offer additional functional added value for those who expect even more from their mattress.

We have provided the base layer with special zoning in the middle that further improves the ergonomics of the Pure.

In order to offer unparalleled sleep quality, even with our entry-level model, we have added body contour zoning to the central base layer. The very functional material, which in itself allows correct posture and correct positioning of the spine, is further enhanced by orthopaedically effective cuts which match the natural shape of the body. They reduce the support force in ergonomically crucial areas of the body. This guarantees appropriate extra cushioning to the shoulders and hips.
