Seat Backs-How to take off!

[knitware]

Hello-Just a quick question.
How do you take off the seat backs to the driver & passenger seats. I have had a brief look but could not see any screws, do they just pop off?
I need to oil the springs to stop the squeaking!
The seats are from a 2.6 CDX.

Thanks in advance!

Two screws on the bottom edge and then they drop down.

A quick job for the weekend!
