<p>A collapsible apparatus (100) is provided that includes a frame (110) configured to form a closed loop, the frame being moveable between a coiled configuration and an uncoiled configuration. A sleeve (120) is configured to receive the frame (110) and to define an opening (200) within at least a portion of the closed loop. An attachment mechanism (300) is coupled substantially about the periphery of the sleeve (120). A fabric member (500) is removably coupled to the sleeve (120) such that it is easily removed. A method of making mats (100) according to an embodiment of the invention includes cutting fabric members (500) from a first sheet of material, cutting body membranes (510) from a second sheet of material (600) such that the amount of excess material from the second sheet of material (600) between adjacent body membranes is minimized (510), and attaching one of the body membranes (510) to one of the fabric members (500).</p> |
