Electric breadknife and a staple gun 
I shaved some of the foam off the sherpa's seat, contact adhered on a layer of closed cell foam (cheap bed roll from the warehouse), and a layer of soft foam (offcut from an upholsterer I think, Para rubber would have something similar though), and shaped it some more. Bought some vinyl from spotlight ($18 a metre - which gives you enough to make two covers), leave it out in the sun to soften the vinyl and staple it to the seat pan (I needed an extra pair of hands for this bit, but did the rest myself).
The road to hell is paved...
