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.
Its standard length is 92 inches while its width is 77 inches. It is relatively larger than a twin comforter, which is commonly 87 inches long and 67 inches wide. On the other hand, it is smaller than queen size and king size comforters, which measure 87 inches to 90 inches long as well as 87 inches to 101 inches wide. To have a relaxing sleep, it is best to use a bed sheet that suits the size of a full size comforter. For a standard full bed mattress, the length of a sheet should be 75 inches while the width is 54 inches. On the other hand, if you have a full extra long bed, the dimensions of the sheet to be used must be at least80 inches by 40 inches.
