Hello, the most important rule when choosing a mattress: the more natural the spine is during sleep, the more relaxed the muscles, the higher the orthopedic effect. How comfortable and correctly selected the mattress will depend on your personal preferences. Someone loves hard mattresses, someone has slept on soft mattresses all their lives, so the “most orthopedic”, but a harder mattress will not bring the desired comfort. As for the manufacturer, Saatva now produces a wide variety of mattresses for comfortable and healthy sleep.
