Using your new King - Sized Modern Loft Platform Bed is a breeze. Just place your mattress on the full decking support system - no box spring needed. The USB ports on the headboard are there for you to charge your phone or tablet while you relax on the bed. When it comes to maintenance, use a soft, dry cloth to clean the bed regularly. Avoid using harsh chemicals as they might damage the brownstone finish. Make sure to place the bed on a flat surface to keep it stable. Also, be careful not to overload the bed with excessive weight. If you have any questions about the bed, feel free to reach out to our customer service.
