Abstract
A bedding structure with collapsible frames, comprising a limiting member, a covering member, and a plurality of frame members. The covering member is connected to the limiting member and has at least one opening. The plurality of frame members are configured in a predetermined arrangement inside the covering member. The frame member further consists of at least two arc curves with one arc curve in close proximity to the other arc curve at its overlapping end. The frame member further contains two adjoining ends in close proximity to the outer edge of limiting member to turn the overlapping end into essentially the highest point and prop up the covering member to a height away from the limiting member. Through the predetermined arrangement of the plurality of frame members inside the covering member, the plurality of overlapping ends are arranged to form roughly a predefined shape, and then through the alignment of frame members and the alignment of arc curves of the frame member, the bedding structure can be folded up for storage.
