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.
If you are purchasing a standard hammock that is 13 ft from ring to ring, excluding the chains, it is best to buy a 15ft stand. Please note that most standard stands are 15 ft in total length. Hammocks have increased in size in the last few years, and it is now more difficult to find a stand under 15 ft.Please also note that hammock hardware and hooks come with the hammock, not the hammock stand.ur small stands accommodate hammocks between 10-12 feet, and are perfect for smaller spaces. If you are unsure which hammocks and stands accommodate each other and prefer to buy a hammock and stand together, then we suggest purchasing a combo package, such as this Hatteras Hammocks combo.
