One of the reasons the couch on the Axis 24.1 is uncomfortable, at least on our 2021, is that the back is too vertical. There is at least 6" clearance in back of it to let it tilt back. I was able to do this by replacing the two hinges at the bottom which are light weight door hinges with heavier ones that I was able to elongate the holes with a round file to let the base go back which allowed the top to go back about 4". It now is much more comfortable.
A pic of the new hinge is attached. The old hinge is to the left and the new to the right. All it takes is about 3/8" more width which results in the top going back 4" more due to the geometry.
