The price-performance test winner, chosen by the independent SIQT Institute (4/2021) - Swiss Brand of the Year 2021.

The happy mattresses were developed for three sleeping positions: supine position, side position, and prone position. The SIDE mattress is designed specifically for side sleepers. It features two integrated firmness levels, a soft side and a firmer side, and is made of high-quality EvoPoreHRC foam. This foam was specially developed for mattresses and offers high climate resistance and support. It is also up to 40% more dimensionally stable than conventional cold foams. The surfaces have special, pressure-relieving cuts in the foam sheets. The breathable mattress cover, made with HCS fiber for optimal moisture transport, also supports a hygienic sleeping climate. The cover is washable at 60 °C.

In the side position, the happy SIDE provides straight support for the spine, as the pelvic and shoulder zones are more elastic. The shoulder, upper arm, and pelvic areas can sink in ideally. The lumbar zone supports the spinal column to prevent it from buckling. In this position, the spine is relieved, and the head is positioned straight, with the cervical spine supported. For this purpose, a pillow with the appropriate height is recommended to fill the area between the shoulder, neck, and head, such as the Side pillow from happy. Thanks to the functionality of zoning, the side sleeper mattress also meets all ergonomic requirements in the supine position. The top of the mattress features cube-cut technology that ideally distributes pressure in the shoulder and pelvic zones, avoiding pressure points and resulting in a pleasant, soft lying feeling. If you prefer a firmer lying feeling, simply turn the mattress over.
