Two years ago now my box spring was getting sort of old so I donated it to goodwill.
Traded some bicycle maintenance for a hammock stand at a local place that sells new goods they buy at auction. Cut it a little shorter and put my Byers of Main mosquito net hammock in it.
Fits in my bedroom fine, and I sleep great in it. Been meaning to sew up another hammock for it that is a better indoor color than green, but other things to do. I can say that at least 300 nights a year for two years, it is holding up well, other than some tears in the net from my Russel mix jumping on me one morning.
Other nights while firing pottery I will set up a tent in my studio so I can watch the kiln. Then its a 25 year old thermarest on concrete.
