A toddler bed is a smaller-sized mattress and frame designed specifically for young children who are transitioning from sleeping in a crib to a regular-sized bed. Toddler beds are typically shorter than full-size adult beds, with dimensions of around 28 inches high by 51 inches wide by 74 inches long. They provide a safe and comfortable sleep surface for young children who may be too big for a crib but not yet ready to sleep in an adult bed. Toddler beds are often decorated with themes or characters that appeal to young children, making the transition from crib to bed more fun and exciting.
