Using your Modrest Liam bed is a breeze. Once it's fully assembled, just place your mattress on the metal slats. You don't need to use a box spring because the metal slats and center support legs provide great support. When it comes to cleaning, use a soft - cloth and a mild detergent to gently wipe the fabric. Avoid using harsh chemicals as they may damage the 100% polyester upholstery. Make sure to regularly check the tightness of the screws on the metal slats and center support legs to keep the bed stable. If you need to move the bed, it's best to disassemble it first to prevent any damage. And always refer to the size options when choosing your bedding to ensure a perfect fit.
