Did you ever get a repair suggestion for your chair?  Mine does the same thing.  I asked someone at a lazyboy store in Houston.  She said they have a lifetime guarantee and that I should bring it in and let them look at it.  It's 50 miles away so I haven't done it yet.  I was hoping that there was some adjustment mechanism somewhere.  Let me know, please if you find some info.   kensterfly at yahoo dot com.
