Thanks but I've used Herman Miller chairs in office environments and they suit my posture, so I'm looking for that specific model

(Or possibly a Humanscale Freedom to compare)

Have you tried London Aerons in New Cross Gate?

@Trunkie - Thanks for the pointer. I'm actually Bristol based, but up un London for the day on Tuesday. I'll try and find time to detour there and take a look.
