Hammocks are the world's most advanced sleeping device. They need no legs and, if secured with a single tether on each end, can rotate violently for comedic effect! Hammocks can also be granted more stability by using a pair of tethers, but this is generally frowned upon as it removes both the soothing rocking and the possibility of violent ejection.
I'm confused. Why "silk" hammocks?
Anywho, I like hammocks but hey are indeed quite dangerous. Two nasty falls from my sneaky toddler of a nephew taught me that.
*Sigh* They're so cute until they master doors...
