So I've done a bit of digging and found severl Lotus owners have replaced the padding in their seats with a special gel foam from the states. It comes in 2 different thicknesses and from what I've read on SELOC and Lotus Talk people seem very, very happy with it.
It looks pretty easy to install, the central sections are just pealed off and then stuck back down. It looks pretty much idiot proof.
Enough foam to do both seats comes in at $70 but postage from the US is quite expensive.
There has been a group buy on SELOC before with a 15% discount and more importantly combined postage. Is anyone interested in joining me in ordering some? If most people's seats are anything like my own the foam if probably well past its best!
