Oh cool thanks for the links... I think the Lotus Probax foam has some kind of lumbar support in it, right? E.g. the foam isn't just flat but has a contour to fit your back, correct?

OEM foam is injection moulded to shape but you can cut/shape your own from sheet foam no problem. Use different densities in layers Firm/med/soft in the right areas (under your butt esp). Google the 3M Conforfoam, you can get it in various thickness's & densities. For adjustable lumbar, get the inflatable OEM bladder part.
