A variant of the hay-spreads or stuffed bags for sleeping were the hung hammocks. The Hammocks are simple long pieces of cloth or nets (like for fishing). A Hammock is a sling, made of fabric, entwined net of twines or woven mats. It is suspended between two or more points on tree trunk, column, wall or ceiling. Hung hammocks forms a very narrow sling, to widen it, both the ends have spacer-sticks.

Hammocks do not need a mattress and one can even do away the pillow. Pillows or head supports are required for head related activities like reading or drinking.

Like all other sleeping devices, mattresses, beds, manch (platform) need a flat resting ground (floor), but hammocks are flying or hanging devices, which just need side connections for hanging. Hammocks can be hung over wet or muddy floors, stock rooms, guns, armaments, stocks in warehouses, between birth in carriages like horse, automobile, railways and space crafts. Hammocks are used for fun, casual swinging, relaxation, siesta, reading, contemplation and slumber.

Hammocks are used in many parts of the world, in varied environments, conditions and for different purposes. Hammocks were developed by native inhabitants of the Americas for sleeping. These were adopted by explorers traveling in wooded regions. Hammocks are collapsible to a small volume and lightweight for transportation. Hammocks have thin body mass, which even, if gets wet, dry out quickly. A hammock covered with net eliminates the chances of mosquito bites. Hammocks do not need mattresses, so there is no fear of dust mites or lice and other contagious skin infections. It also provides safety from insect stings or animals bites like snakes, mosquitoes, ants, bees, etc.

A hammock experiences three types of movements, 1, the swinging motion, 2, micro changes due to the breathing, 3, twitching, due to the shifting of the body posture. Hammocks were adopted by sailors, as its capacity to swing counters the sickening motions of the sea waves. Later, these were used on marine vessels. Ordinarily the rocking motion of a hammock is unnerving, but once accustomed, it encourages deeper sleep.

Swinging motion speeds up the change from wakefulness to the deep sleep (stage-2 sleep). Sleeping in a hammock relieves the pressure on body muscles, as it allows minor adjustments of tissues and body-fluids. There is equal distribution of pressure on all parts of the body, as the surface of the hammock is stretchable and flexible.

Royal navy in 1597, for the first time mentions the hammocks as ‘hanging cabbons or beddes’. Hammocks were preferred over fixed bunks, as could be hung between-over the guns, rope coils or wet floors. Hammocks require no mattresses, and so were ideal against proliferation of skin deceases among sailors (due to vitamin C deficiencies). During the colonization of the 17th C, the hammocks became a world-wide a marine facility. Hammocks have also been employed on spacecrafts in order to utilize available space.

Hammocks allowed comfort and maximum utilization of the cramped space in temporary army tents. Hammocks are used as a lightweight bed for tropical climate explorers. The advantages of the snug Sleeping bags for colder climate campers and mountaineers are of different class. Hammocks have a sleeping facility that is of a thin body fabric or net structure and off the ground. This creates an air movement system around the body, same as the Indian Charpai.

Early hammocks of Latin Americas and other pacific islands were of local materials like woven tree bark fibers and sisal fibers. These were soon replaced with cotton and other fibers, spun into ropes. The salvage (ends) of the fabric needed extra reinforcement. For these the warp-yarns at the edges, are made heavier and stronger, alternatively annealed copper or steel wires are used. The edges are also stitched as doubled seams. Net weaves or basket like constructions, also need edge reinforcement besides extra strength in sections where the buttocks of the body exert high stress. Another issue is keeping the hammock wide-open, for sleeping side ways. These is achieved with use of spacer bars, pipes or sticks at both the ends.

Children Palana or Zhula (India) cradles or Ghodiya (Gujarat India) provide the movement experience similar to a hammock. There are two major configurations, Flat beds offer only the swinging motion, but hammock style curved ones, bend the body in the manner of a mother’s womb. Best or popular movements are sideways but some contraception permit movement in head to feet direction. A bassinet, bassinette or perambulators, are baby carriages, with some additional facilities like head-shade, shock absorber springs and wheels. The springs are soft (spaced spirals of compressible springs) that generate extra vibrations to compensate, for the hammock like movement.

In India, Sarees, Dhotis and bed sheets are used to function as a hanging hammock. Injured patients, dead bodies and colonial officers, in hilly travel were carried, through hammocks hung from a long horizontal mast (a sleeping palanquin). Patients and dead bodies are carried in hammocks (called soft stretchers) through small stairs or elevators (which do not allow full length stretcher or coffin). The shroud is used as a hammock to lower the body in the grave. Hammocks have also been employed on spacecraft in order to utilize available space.

Two-way woven fabrics, through knitting mode eliminates the strength differential (and stretching capacity) in weft-web directions. Hammock pose many risks. This may include, neck and back pain, limited space shape for stretching, fixed or limited posturing, risk of falling out and difficulties of getting in or out.
