I'm getting armache reaching over to my X52. A better solution is required. I have in mind something like Zorbulev did here: https://forums.frontier.co.uk/showthread.php?t=12745
which used two of these:

to do this:
As you can see, the VESA mounts are designed for pole mounting. They grip Zorbulev's chair well enough but I doubt they'll work on mine. This is the chair I'm using:

The armrests are about an inch wide and 2mm thick. The armrest verticals are ever so slightly curved, but nowhere near as much as it appears from the photo. An identical mounting with flat grippers would be perfect - if such a thing exists. I've no idea where to start looking, really. Can anybody help me out please?
