I have a newer chair on my PH chair and it's bigger/longer base than the stock chair so I need a longer footrest (preferably one that folds). The stock one isn't quite long enough to put my foot on and my leg starts to go numb after a while (by product of too many spine surgeries too). Has anyone found anything out there that bolts on to the post of the helm chair (I believe it's 4") and extends out further than the stock Zwardies chair footrest?

Thank you!
