Accidentally spilled about 20 ounces of bathroom cleaner in the back seat of my 2009 CLK 350 (loose cap on the container, on the way home from the store -- be careful!).

Trying to get the seat cushion out to get at the mess. The back of the cushion was simply tucked under the seat back, but trying to figure out how to unhook the front edge.

Anyone?

Thanks.

 

To lift the bottom of the rear seat, which is what I think you are asking, look for a black plastic loop on the outside of the seat against the side wall. Pull the tab and lift the seat from the back. It will tilt forward.
Good luck
