My old hammock hanging after years of use by very, so I wanted to buy a new one. The dimensions of this hammock agreed exactly with those of the old. I also thought that the plastic materials could be more dimensionally stable than cotton, so I ordered it. I use my hammock on a stand and trying out then was the big disappointment: my old mat was firmly against it here. The substance is apparently somewhat elastic, which has the effect that the mat pretty sags (I am normal weight), much more than the baggy old, and I rested just on the lower bar of the frame. They therefore had to go back. In addition, the wooden bars were not processed as beautiful as my old mat, they seemed not to be sanded. The mat may be suitable for those who they hang relatively higher on a tree, but not if they used one with a frame. I think my frame has the standard dimensions, it is not, however, be adjusted.
