piano bench knob stuck

[kawai_cs]

I am sorry for this silly question but I have had a problem with it for several days.
Some time ago I bought a piano bench and set it to the highest possible position. Now I need to go down and the knob is stuck. I do not have enough power in my hands/wrists to turn it and I do not even now which direction to go because it does not move at all. Is very any way to slacken it off?

1) Can you take it apart so you can see how the mechanism works?
2) Have you tried google?

1) No, I am a woman. I would never be able to put it back together again.  
2) Yes, but I did not find any helpful information, just to lubricate it, or bend rails into position.

I thought maybe somebody knew a trick like the one with opening a tightly closed glass.

Try using a mousepad to grip it, perhaps? Worked for me when I used to have an artist bench

Turn the bench upside down so you can see the mechanism and put a pair of pliers or, even better, a self-grip wrench ('Mole wrench') or pipe wrench on the middle of the lead screw.
