Noble Hero-Recline Dial

[Stevethedoc]

I've just bought a Hero in full leather-best chair I've ever had.

I just wanted to check about the big twist dial underneath which is supposed to alter the stiffness of the recline. I've had other chairs and all it takes is a couple of turns and you can really feel the difference in resistance to reclining back.

On this one, it seems to turn forever (I've never reached a stop) and for all those turns it makes only a slight difference-Is that how they are?

I've tried turning the knob both ways, it does get stiffer but then looser, it doesn't feel light tightening a screw which gets tighter one way and looser the other. I can turn lots and it doesn't seem to reach a stop point in either direction?

Thanks for any advice.
