Shes all I can afford so I throw everything into her
First I'm going to file any burrs out, round the edges, and then get some auto door trim and wrap it around the aluminum edge, especially around the head and shoulder areas. The cushions haven't been mounted yet but they'll be mounted slightly over this edge so there is no chance for a lancing if I get some kind of whiplash. It all sounds a little scary but I'm confident it'll work out.
I'm only 5'9" but I can still sit comfortably in a half seated/ half stance position. If this doesn't work out I can always cut the lower part of the pod down to reduce the height and have someone re-weld the base. I will post the progress.
