Hammocks sure have come along way since they were just pieces of rope tied between two poles or trees. Now hammocks or sky chairs you might say come already attached to poles or supports of some kind and can be easily moved from one place to another. Personally I do not see how people used to lay or even sleep for several hours in hammocks of the old design.
