First-world problems!
My knees start hurting, so I put up the footrest, and it immediately drifts to one side or another. I reach out and straighten my recliner, only to have it immediately drift again.
I don't want to disable it completely, I needed to climb over the side of my old recliner.
I don't want to go back!
I keep visualizing some kind of hand brake... for a recliner!
