Bolster seat dropping ??

Problem one bolster seat starts to drop down ever so slowly.

It does it again ever so slowly just creeps down???
Are there any adjustments to anything?

The problem is with the hydralic tube under your seat. After a time they will leak internally allow fluid to pass through the oriface. If your interested I have a couple of them, with the buttons and cables I'll part with. I pulled them out to put in an electric actuator set up. One of the tubes is still good, the other has the same issue as yours.
