These are sold at more out of the way stores specializing on the locally made product. My hammock came from Hamacas WMS (With Mexican Style), a socially responsible, local industry promoting Yucatan goods. Visit their website here. And forget the $200 peso price tag. Yucatan hammocks go from $650 pesos on up.
This is how they attach to the tree. The rope (provided) is fitted with a steel "S" hook. Simple.
Now, let's look at a store. We found this place quite by accident while we were lost in Merida looking for Hamacas WMS. No matter, we went on in because we were getting ready to head north to the States and Indra wanted to get one for her son for his birthday.
Note that they advertise sales, repairs and cleaning. Full service.
There is no end of sizes and colors......
And you can get hammock chairs.....
The saleswoman was very helpful, unwrapping and showing the sizes and colors.
So, if you're approached by someone selling hammocks on the street, think twice. Spend a little more money and get the real deal. They are comfortable and, with the proper care, will last a very long time.
Now, for a very detailed look at the Yucatan hammock, I'm going to steer you to a site called Hammocks of Yucatan. This guy makes my effort look puny, but I figure why plagiarize or reinvent the wheel.
