I have a couple of dining room chairs from IKEA, which have been quite good for a number of years.
One of them, however, has started wobbling a bit, and I saw that it was because the back of the chair is no more strongly fixed to the frame.
I am trying to disassemble it, but the latch/joint that is used, I can't understand, how should I remove it.
As you can see in the image, it is 2 metal parts, which slide and probably click into each other (it was ages ago when I assembled it, so I don't remember):
However, I can only put in a very short length of screwdriver inside, there doesn't feel anything much there and I am concerned I might break the screwdriver if I pushed harder.
Any ideas how to dismantle this?
