Abstract
Portable structures convert into furniture articles, such as chairs, backrests, and tables, when substantially filled with sand and revert to collapsed portable structures for easy transport after a substantial amount of sand has been removed. The portable structures include a cover, made from a flexible and deformable material, and a frame that includes one or more flexible frame members disposed on or incorporated within the cover. The flexible frame members have spring-like characteristics such that a portable structure, without substantial sand therein, can be collapsed for storage and/or transport, and when ready for use, automatically converted to an “uncollapsed pop-up” state adapted to receive sand filling to form the furniture article.
