I believe that's a typo and you meant Amazonas.
Having seen the knobs at the side on the Vario knock-off, I would put this a the top of my reasons to not get this one. Those knobs in the middle are painful...especially if you were to fall on them.
What I've found is that the stretch of the hammock (or the suspension) has got me to where I can feel those ##$$$$@@@! knobs. I put an el cheapo lifejacket over them, but sure wish the knobs were at the side.
