Similar to https://www.reddit.com/r/fixit/comments/1btyyg3/lazboy_ergonamic_mesh_chair_lumbar_pad_came_off/ my lumbar support fell off on my La-Z-Boy Ergonomic Mesh Swivel Task Chair model 60021 (Joel). The lumbar support was always loose and had to constantly be readjusted to where I wanted it.
The problem
- The single screw that holds the padding to the lumbar support arm backed all the way out which caused it to fall off.
- There is no apparent way to easily reattach it
The solution
- remove the arm the padding attaches to by removing the 2 screws with an allen key
- separate the padding from the plastic backing by carefully pulling them apart until the 4 posts pulled out of the padding (one in each corner)
- attach the plastic backing to the arm using the plastic adjuster, locking washer, and screw
- I screwed it in really tight, but if you have some thread lock you may want to use it
- snap the padding back onto the plastic backing by pressing it into place
- reattach the arm to the chair
The result
The lumbar support is reattached and now much better at staying in place (better than new)
Update: Since I did not use thread lock the lumbar support has loosened some
