The Biocrystal Selenium 27 cm mattress is designed to promote deep, balanced and restorative sleep by combining ergonomic comfort with advanced wellness technologies. Its fabric integrates Biocrystal®, Turmal.ink and Electrostatic Balance technologies, developed to help reduce stress, improve relaxation and neutralize static electrical charges that can affect sleep quality. The tourmaline component releases negative ions that help counteract electromagnetic overload from everyday devices, promoting a greater sense of well-being and more refreshing rest. The mattress includes a 2 cm memory foam layer combined with Supersoft foam and Todotherm fibers, providing excellent body reception, pressure relief and proper ergonomic posture with medium-high firmness. Its high-density HR core ensures stable support and durability, while the Pressure Care System with 12 zones distributes body weight evenly to reduce pressure points. Manufactured with hygienic treatments and certified according to European standards, the Biocrystal Selenium mattress provides durable, comfortable and technologically advanced rest. Made in Spain.
