QuadRemesh - Quad Remesh failed to create a mesh


I am unable to get a mesh quaded using QuadRemesh command.
What is wrong here (beside the issue between a chair and the screen).

I will deeply appreciate any piece of advise.
(there is no option to attach a file?)

has to be a mesh that actually encloses volume, your mesh is flat.

instead extract the border, break it into 4 curves and then simply run a 2 rail sweep, or grab the two long curves, rebuild them to be subd friendly and then loft them with the subd loft.
