A rollaway bed is a portable bed that can be easily folded and stored when not in use. It typically features a metal frame with wheels, allowing for easy movement. Rollaway beds are often used in hotels, guest rooms, or homes to accommodate extra guests without taking up permanent space. These beds usually come with a thin mattress, making them suitable for short-term sleeping arrangements. They are designed for convenience and can be set up quickly, providing a practical solution for unexpected visitors or small living spaces. Rollaway beds are also known as folding beds or portable beds.
