A Japanese platform bed is a low-profile bed whose bottom sits closer to the ground than those of most other types of beds. Designed to be used without a box spring, it requires only a mattress.
Japanese platform beds may or may not be designed without a headboard or backing. They have four legs and are elevated but remain close to the ground. The platform serves to replace the box spring in other bed designs. The platform can be of varying sizes, and it sometimes extends well beyond the dimensions of the mattress. These beds are commonly built of wood or bamboo.
