Hammocks: An Anatomy Lesson

If you've never settled into a hammock on a lazy summer day, you may be surprised at just how comfortable they are. They don't just have the cool factor, they're quite literally cool because the open weave or lightweight fabric used in their construction allows the air to pass through instead of trapping your body heat. That's just one of the many things you should know about hammocks if you're considering buying one - or a pair - for your patio or guest room. Knowing the parts of a hammock and how they all work together can help you wade through the myriad hammocks available on the market. Here's what you need to know about the materials, workmanship and construction of hammocks to help you make the right choice for your needs.
Rope
When you think of a hammock, you probably think of rope, if only because it makes up the largest part of the hammock. In fact, it is possible to make a hammock completely from rope. There are a number of options for rope materials, including cotton and spun polyester blends. While cotton is the most traditional choice for hammocks, spun polyester is often a less expensive and sturdier alternative. Unlike cotton, spun polyester will stand up to most weather extremes without mildewing. It also tends to dry faster than cotton and other materials, making it an excellent choice for hammocks on patios and porches and in backyards.
The rope is used for the eyes - the loops at either end of the hammock from which it will hang - the guy lines, which are the parallel rope lines that run between the eyes and form the lengthwise ribs of the bed, and the bed itself, which is the woven center of the hammock in which you sit or lie.
Hardware
The material used to hang the hammock is as important as the materials from which it's made. In most cases, hammocks are installed using metal hardware, consisting of chains and eye rings. For strength, look for quality chains of zinc-coated steel. The ring and chains should be permanently attached to the hammock, and the mounting point should be installed in a solid beam or hung on an appropriate frame.
Spreader Bars
Many hammocks have spreader bars to hold them open at either end. The spreader bars are most often made of wood, though some hammocks are made with metal spreader bars. Wood should be varnished with marine varnish (also known as spar varnish) to protect it from the elements. 
Hammock Stands
Most backyards don't have trees in the right places or the appropriate distance apart to hang a hammock for the ultimate in bucolic bliss. These days, it's more common for people to buy hammocks with stands. Stands may be made of metal or wood, and come in a variety of configurations and styles. When choosing a stand to go with your hammock, be sure to choose the right size and to choose one that will support at least the amount of weight that the hammock is rated for.
Hammocks and hammock chairs are among the most comfortable options for sitting, lying, relaxing and sleeping. Take the time to carefully examine every part of the hammock you're considering in order to be sure that you're getting a high quality hammock that deliver blissful, relaxing comfort.
