LOL! In Charleston SC there is the "ocean hammock" which is like this but a mattress.

Truth be told the porch swing was based on this very thing. Southerners are quite innovative (e.g. cotton gin, first submarine, race cars, and Jim Beam). LOL

I have to clean my glasses. I thought bluridge said submarine races, which is a popular sport on the coast.

I love it! Hey, Rednecks gotta "relax" too.
(I'll have to look for the mattress swing).
