The mattress has 620 springs and is made up 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! LED headboard with USB & Type C: One of the most convenient features is the built-in power outlet at the head of the bed, which allows you to charge your mobile phone and tablet before going to sleep. In the storage compartment behind the bed, there are two USB ports and a Type C outlet. App-Control LED: Unlike regular LEDs, this bed is equipped with LEDs that can receive a wider range of signals, a color-changing light strip, and a music mode that enhances the sleeping experience. You can easily control different LED lighting modes via the mobile app. Please note that it is not possible to play music. Headboard with storage space: Three storage compartments are located on each side of the back of the padded headboard. The storage compartments feature a gray artificial marble pattern that provides a classic and pleasant look. Thanks to the gas lift support, the space under the bed slats can be used to store large items. Detailed information: To reduce the risk of damage, this bed frame is shipped in 3 boxes, and these may arrive on different dates. If both packages have arrived but there are missing parts, please contact customer service. If you are moving the bed, please lift it instead of dragging it across the floor. Before returning the product, please contact the seller first. Thank you for your understanding.
