A convertible sofa, also known as a sofa bed, is a versatile piece of furniture that can transform from a sofa into a bed. This design is ideal for small living spaces, allowing homeowners to maximize functionality without sacrificing style. Convertible sofas come in various styles, sizes, and materials, making them suitable for different decor themes. These sofas typically feature a mechanism that allows the backrest to fold down or the seat to pull out, creating a sleeping surface. Many models also include built-in storage for bedding, enhancing their practicality. Convertible sofas are popular choices for guest rooms, apartments, and multifunctional spaces.
