The Biocrystal Selenium 30 cm mattress is an advanced wellness sleep system designed to provide deep, balanced and restorative rest by combining ergonomic support with innovative technologies. Its fabric integrates Biocrystal®, Turmal.ink and Electrostatic Balance technologies, developed to help reduce stress, enhance relaxation and neutralize static electrical charges that can affect sleep quality. The tourmaline-based fabric releases negative ions that help counteract electromagnetic overload from everyday devices, promoting energetic balance, well-being and more refreshing sleep throughout the night. 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 and adaptable comfort. Its high-density HR core ensures stability and durability, while the Pressure Care System with 12 zones distributes body weight evenly and helps reduce pressure points. Manufactured with advanced hygienic treatments and European certification, the Biocrystal Selenium 30 cm mattress offers durable, comfortable and technologically optimized rest. Made in Spain.
