Some appliances feature a reversible door that allows you to change which way the door swings open. This lets you customize your appliance to fit the room it's in. For example, you can streamline your laundry space by making sure the dryer door isn't in the way when you transfer clothes from one machine to the other. Or, you can adjust the way your refrigerator opens so the door doesn't bang against a wall or cabinet. If you're left-handed, reversing your appliance door could make it more comfortable to use.
