If you're looking for ways to keep your mattress in the living room without it looking out of place, there are a few things you can do. First, consider finding a bed frame that matches the style of your living room furniture. This will help the mattress blend in with the rest of the room. You can also try using a daybed or futon as a bed frame, which will give the room a more relaxed feel. Finally, be sure to keep the mattress clean and free of wrinkles or stains by using a mattress protector and regularly rotating and flipping it.
