Wall beds, also known as Murphy beds, are space-saving furniture designed to fold up against a wall when not in use. This innovative design allows for more floor space in small rooms, making them ideal for apartments, guest rooms, or multi-purpose spaces. Typically, wall beds come with a mattress and can be easily pulled down for sleeping. They often include additional features like built-in shelves or desks, enhancing their functionality. Wall beds are a practical solution for maximizing living space while providing comfort and convenience.
