Whether you choose a hammock with or without spreader bars depends on your personal preferences. Both are well suited to relax and recreation.
People in Brazil and other countries in South America, however, almost exclusively use cloth hammocks without spreader bars.
The advantages of a hammock without spreader bar are obvious:
* easier wash ability (also in the washing machine),
* more flexible in the transport and lighter
* more stable in balance
* Hammock adapts better to the body and
* something cheaper in price.
