if i was going to spend the money that that bed costs i would get one of these.. http://www.floatingbed.com/index.html
you know HHB, you're a resourceful and handy SOB, i bet you could make a very comparable bed for far less money than it would cost to get the factory made one. shouldnt be too hard at all, really. for me the biggest question would be how to get such a large ring, but i'm sure theres a way i just don't know of
I like, I thought of something like that for outside like a large hammock. I dismissed the idea. Im dumb.
we have one of these someone forgot here a while back. http://hammockshop.com/catalog.php?id=8&d=1 great for a nap but i dont think id wanna sleep on one all the time..
a pipe bender and 36 feet of twi inch diameter steel pipe some mig welding when you're done or, a local machine shop.
you could also do it with properly crimped and bent metal fence posts, but you'd want to weld the joints. it would also be pretty easy to do a non circle with other materials like track rails (you know, like hanging displays are hung dfrom, it's rectangular, has bolt holes in the back, two hook around "rails" on the front, you could make bends by taking an angle grinder to it, and bending it incrementally, around the radius.
see, i knew there had to be simple solutions that i just was unaware of. come on, HHB. if you want that bed, you can have it, easy. it does look pretty badass, and its totally within your abilities. i bet you could make it even cooler, too.
