Using your new Modrest bed is a breeze. First, assemble the bed following the included instructions. It requires some assembly, but don't worry, it's not too difficult. Once assembled, place your mattress on the slats. You don't need a box spring as the slats provide good support. For different bed sizes, make sure you choose the right - sized mattress as specified. When it comes to maintenance, use a soft cloth to wipe the black velour regularly to keep it clean. Avoid using harsh chemicals that could damage the fabric. The champagne - gold stainless - steel legs are durable, but you can gently clean them with a mild cleaner. If you need to adjust the bed, you can easily remove the slats as they are adjustable. Just handle them carefully during the process.
