The space in the thoracic cavity between the concave inner surfaces of the lungs, in which (in a special pericardial cavity) the heart is located, is called the mediastinum. The thoracic cavity is lined with a serous membrane called the pleura. The lungs are enclosed in the so-called pleural cavities, which are separate in man but communicate with one another in the majority of mammals. The shape of the thoracic cavity depends upon the shape of the thorax and the position of the diaphragm.
We sell 5 hammock sizes on the Traditional Hammocks (no spreader wood bars). Therefore, the length of the hammock is the same for each size but the difference is the width. Width gives the size. The larger the size, the wider and bigger the hammock.
Bar is a double. 50 on up are larger doubles. In bar hammocks the length of the hammock overall is a significant variable as it determines what size hammock stands can be used. Hammock stands are generally sized at super-short 10', medium 12' or 13', standard 15', and Large 16'.elow, I am charting the Mayan Hammocks by name, size and width. We measure width as we lie across the hammock from within the hammock. This is the only useful way to measure. Some folks have two guys stretch an unhung hammock as far as they can across the middle, and then tell you their Super Jumbo is 14 feet wide.
