Spreader Bar Hammock - Single
Spreader Bar Hammocks For One Person
There are several advantages to a hammock that features a spreader bar, the first and may be the most important to some individuals is it is easier to get into.
Another reason is the surface area is spread out more allowing sunshine without shadows for the sun worshippers, especially when they are sun bathing.
Since you have more surface area it is also a little more comfortable for more than one person, generally the spreader bar hammocks are hung a bit more taunt that one without bars.
