Nothing beats the lazy sway of a hammock on a sunny summer afternoon. A hammock is simply a sling made up of twined rope or strong cloth. Hammocks are come in various styles - such as chairs or loungers, single, double or king-sized, framed or hammocks that must be anchored to a tree. If you don't have trees or a hammock stand you can purchase hammock stakes which need to be cemented into the ground. Hammocks are also offered in an array of fabrics and colors such as popular Navajo, Mayan or South Western patterns. The price range for hammocks is extremely vast, from $30 to $200 online, depending on the style and design.
