The mattress has 720 springs and consists of 2 layers of foam that are not only soft but also supportive and comfortable. We use textiles free from harmful substances, tested according to the Oeko-Tex Standard 100, which are safe and non-allergenic! LED headboard with power outlets & USB ports: One of the most practical features is the built-in power outlet in the headboard, allowing you to charge your mobile phone and tablet before bed. Each outlet features two standard EU charging sockets and two USB ports. App-Control RGBW LED: Unlike ordinary LEDs, this bed is equipped with LEDs capable of receiving a wider range of signals, a color-changing light strip, and a music mode that enhances your sleep experience. You can easily control different LED lighting modes via the mobile app. Please note that it is not possible to play music. Solid construction: The main frame is made of iron and ensures the stability of the bed with a weight capacity of 440 lbs. The slats are made of elastic solid wood and provide comfortable support for sleep. Detailed information: To reduce the risk of damage, this bed frame is shipped in 3 cartons, which may arrive on different dates. If both packages have arrived but parts are missing, please contact customer service. If you are moving the bed, please lift it instead of dragging it on the floor. Before returning the product, please contact the seller first. Thank you for your understanding.
