The mattress has 620 springs and consists of two layers of foam that are not only soft but also provide support and comfort. We use textiles free from harmful substances, tested according to the Oeko-Tex Standard 100, which are safe and non-allergenic! Adjustable headboard: the padded headboard is filled with high-density, thicker foam, allowing you to relax comfortably while leaning against it. The height of the headboard is adjustable, with a height adjustment range of about 12 cm. People of different heights can find their best comfort point by adjusting the height of the headboard. Charging station with power outlets and USB ports: one of the most convenient features is the built-in power outlet at the head of the bed, allowing you to charge your mobile phone and tablet before going to bed. Built-in USB/Type-C ports and European sockets are located at the head of the bed. Flexible and spacious storage: the 50 cm high headboard features a cabinet design with four spacious compartments. For clothing storage, four rolling drawers can be found under the bed. Thoughtful details: the slatted bases are 100% made of solid wood and metal, providing both high load capacity and great sleep comfort. The soft materials of the bed not only provide a pleasant feel but also effectively reduce damage caused by sharp corners and edges that you or your family could experience during use.
