Hello. I've looked around and haven't found this question in the forums.  Is there a way to center jack on the screw rod to raise one side only to level it?  I have a client with a new adjustable bench.  With the knobs on the side that turns a screw lift.  One side is noticeably lower than the other.  The measurement from the bottom of the seat to the top of the frame is about 1/2 inch different on one side.    Since the screw moves the scissor jacks the same, the only thing I can think of is repositioning the lift brackets on the side of the frame.

Hi Robert,

Which brand/model adjustable bench are you dealing with? If it's Jansen, you might try calling them. If they aren't sufficiently helpful, there are a number of folks familiar with maintaining the mechanisms here (or in the CAUT forum).

Good luck! 

Robert,

If it does not look like a simple fix, and it was purchased on line, I would suggest returning it as defective. 

That said, I altered one fellow's adjustable bench (that was irreparable wobbly) into a non-adjustable form at the height he liked by cutting identical shims (blocks) attached between the lower frame and the seat frame. Now very solid. 

If it's a cheap bench...well it's cheap. If not, as Pat said, there's help a phone call away.

Thanks for your replies.  At my Guild meeting last night we remembered furniture leveling feet.  Something along these lines.  https://www.amazon.com/adjustable-furniture-levelers/s?k=adjustable+furniture+levelers
