Using this daybed is a breeze. First, if you want to use the trundle for extra sleeping space, simply lift it up and unfold the legs. Make sure to place a suitable mattress on both the daybed and the trundle as they are not included. When you're done using the trundle, fold its legs and tuck it under the daybed. As for maintenance, regularly dust the metal frame with a soft cloth. Avoid using harsh chemicals or abrasive cleaners as they may damage the finish. Keep the daybed away from direct sunlight and moisture to prevent rusting and other damages. If you notice any loose parts, tighten them promptly to ensure the daybed's stability and safety.
