Splurge and get yourself an Xtra large, high quality, Hatteras style hammock that will support 400 - 500 lbs (I think ours came from LL Bean or Land's End). The right kind will have *ahem* spreader bars and a tubular metal stand. Ours has lasted a good 10 years w/no maintenance with some of those years in harsh desert sun, and several more in coastal salt air.
The trouble with having an open mind is that people put things in it.
