New drivers seat squab foam wanted - help

Hi
Hopefully a straightforward question;
I have a 2000 'W' 2.5 DHSE, 80k and the outside edge of the drivers seat squab has seen better days, looking a bit 'compressed'.
I'm looking to replace the squab foam (and possibly the heating elements) but trawling Fleabay has do far failed to reveal a new foam squab.
Will I have to resort to buying from a Main Stealer (£100?) or can anyone point me in the right direction please?
Many thanks
Andy
Ps, I'm registered disabled with a crumbling spine so bending over for more tha a few seconds is almost impossible; is it a straight forward job or is there anyone local to me who would do it for some beer tokens (5 mins from J 29 of the M1, near Clay Cross, Derbyshire)

Find a motor trimmers shop near you and he may be able to cut and fit you a new foam pad maybe to your specs as well.

Thanks, may have to resort to that.
Do main dealers or specialists keep the foam squabs at all does anyone know?

Have a word with this guy

eBay - The UK's Online Marketplace

Thanks, just messages him via Fleabay to see if he's got the new foam that you sit on; you never know...
