Hi @kellie.hamre,
let me know if this block is what you are looking for.

If so, here are the steps I took. It looks complicated but total time was about ten minutes:
1) I converted all the faces to surfaces using CONVERTTOSURFACE ( I selected everything all at once so this was pretty fast)
2) I used VIEWBASE to create a plan view in paperspace
3) I next ran EXPORTLAYOUT to create a new drawing in 2D of the layout data.
4) I opened my new drawing and this is where things get slower.
5) I used OVERKILL to remove coincidental linework.
6) Since this was symmetrical,I erased the bottom half of the chair.
7) I then erased linework that was contained within overall shapes.
8) I used BOUNDARY to create polylines inside each of the clean shapes.
9) once all my boundaries were created I erased everything else.
10) I mirrored my boundaries to get the bottom half of the chair back.
11) I then turned the linework into a block.
