I love the Pub Prop!
It attatches to anthing that has a horizontal surface so its not just for the session monkeys.
I work on ships and i use it to stop my mandolin falling on the deck and turning into firewood.
Suitable for fiddles, mandolins, banjos, guitars... pretty much any stringed instrument with a neck the size of a guitar or smaller. It also comes with rubber adaptors to fit (i.e one with a tighter curve for the fiddle, a flatter one for ukes etc)
it comes apart for easy storage in youre instrument case, and takes a few seconds to assembe and prop!
In summation, play an instrument like the ones above? yes? Buy this and worry no more about someone sitting on youre beloved noise making apparatus! Happy Propping people! :)
