Jim Langley's FAQ there are instructions for making a sling saddle type seat using a stem, handlebars and some denim!
This is what he has to say:
"Here’s a picture of the original sling saddle as built and ridden by the inventor and noted cyclist, Dan Henry. For a while this seat was sold as The Bummer, but, as far as I can tell, it’s no longer available.
So my recommendation is to make your own. The construction is pretty straightforward and shouldn’t cost much. All you need is a stem and drop handlebars that fit together. You could use whatever’s available, maybe stuff purchased at a flea market or swap meet or even at the dump.
Assemble the stem and the bar as shown in the photo and cut and sew some dungaree material or canvas or nylon webbing or what have you, to form the sling that slips over the flat portions of the handlebar. The tricky part will be making the stem fit inside the seat tube on the frame. You’ll probably have to shim it. There are many ways to do this.
The cleanest is to get a piece of tubing and turn the outside and inside diameters down, the former to fit the frame and the latter to fit the stem, which is now the seatpost. Then slot the tubing shim you’ve created so when you tighten the seatpost binder it’ll grip and hold. I imagine a machinist could make such a shim for an hour’s worth of labor. Or you could just fashion a shim out of anything you might have around the house. It shouldn’t be too difficult to find something that works."
Just think you could fabricate your very own "Bummer"!
