Abstract: A birthing stool is disclosed comprising a series of closed walls constructed from a non porous rigid material, molded into compound curves. The stool facilitates a range of physiologically effective positioning for labour and delivery and can be used submerged underwater during waterbirth. The stool ergonomically supports the body while also achieving structural integrity through a simple organic form that can be produced inexpensively using minimal material. All elements of the stool, including a seat portion that accommodates a labouring woman and her birthing partner, as well as handles and grips for carrying are integrated into a single part design, facilitating effective cleansing and disinfection of the apparatus. The invention includes the method of production of the stool, and describes method of using device.
