Product details
The price-performance test winner, chosen by the independent SIQT Institute (4/2021) - Swiss Brand of the Year 2021.
The happy mattresses of the UP/SIDE/DOWN line were developed for three sleeping positions: supine position, side position, and prone position.
The happy DOWN mattress is the model for stomach sleepers.
In the prone position, the happy DOWN supports the body in such a way that sagging of the spine is avoided, which would lead to a hollow back. A slight crowning of the abdominal zone provides fine support for the upper body, while the rib cage remains free of pressure to prevent pressure points in this sensitive area, allowing for free and undisturbed breathing.
The two sides of the mattress, one softer and one firmer, can be selected according to the desired lying sensation.
The surfaces each have special, pressure-relieving cuts in the foam sheets. This ensures that pressure on the chest and pelvic area is ideally distributed, eliminating pressure points that can cause changes in sleeping position. Sleep phases can be passed through undisturbed, resulting in better recovery and well-being.
The high-tech EvoPoreHRC cold foam is particularly breathable due to its open-cell structure. Its production requires 30% less material than conventional cold foams and it is 40% more dimensionally stable than cheaper alternatives. This means special longevity, sustainability, and excellent moisture absorption.
The breathable mattress cover with HCS fiber for optimal moisture transport also supports a hygienic sleeping climate. The cover is washable at 60 °C.
To ensure correct and straight posture of the head and cervical spine and to avoid overextension, which can lead to shoulder and neck tension, it is recommended to choose a pillow with a very low height in this position. For example, the happy DOWN stomach sleeper pillow from happy.
