The prototypic mountain tents are assembled on rocky, mountain slopes with inclines up to 35 degrees. The individual tent has a horizontal, artificial 4x4m plywood floor and is supported by a tubular aluminum framework standing on extendable legs. The aluminium framework forms a grid of two squares on each of the four walls. Canvas roofs form four sided pyramids and serve as interior ceilings. The tent walls contain one door and a window that may be propped open for ventilation and viewing.
