This feature in it is because of presence of a curved headboard and footboard that is outwardly curled at each end’s top. This footboard is often found to be shorter than the headboard. History records suggest when these were used traditionally; it did have a feature imbibed in it because of which it could curl inwards as well as outwards.

The objective behind this was to highlight it as one of the primary pieces of furniture of that particular room. Generally, people took immense pride in showing their prized possession.
