The mattress has 720 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 a thick, high-density foam, allowing you to relax comfortably against it. The height of the headboard is adjustable, with an adjustable height range of about 12 cm difference. People of different heights can find the best comfort point by adjusting the headboard height. 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 sleep. 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 wheeled drawers are located under the bed. Thoughtful details: the slatted bases are made of 100% solid wood and metal, providing both high load capacity and great sleeping comfort. The soft materials of the bed not only provide a pleasant feel but also effectively reduce damage from sharp corners and edges that you or your family might experience during use.
