Source for Gaucho bed frame?


Hey all,

Posting here as I know there are some people who may be able to help me out...

Many of the Pop-ups and conversion van companies sell 'guacho' style couches that convert to a bed. The backrest spins and flips down to the form the bed. It seems that the "flip" mechanism is similar with all of them, and I'm thinking it must be something off the shelf? Anyone have any insight into this? This would be for a home-build...

Any help would be appreciated!
