As above, I am in the process of dismantling my HLX seat in order to re-cover my new one.

I get the general idea of what to do although one bit is puzzling me; the tilt and slide handle that you lift in order to gain access to the back seat.

I have removed the screw from the bottom but it still won't budge, any one have any idea how to remove it?

I don't need it removed completely, just enough to get the cover out from behind it.

Try this link, should answer your question with pictures.

You're a star, cheers.
