A bed is a fundamental piece of furniture designed for sleeping and resting. It typically includes a mattress, a supportive frame, and sometimes a headboard or footboard. Beds come in various sizes, including single, double, queen, and king, catering to different space and comfort needs. Materials vary, with options like wood, metal, or upholstered frames. Beds are essential for a good night's sleep, providing comfort and support, and play a key role in bedroom aesthetics.
