Tried my hand at some concept furniture design, looking for feedback

I'm training to be an architect, and wanted to try my hand at some concept furniture design for a change of pace. The idea was to pair a raw structural material, in this case, cut sections of I beam steel, with softer and rounded forms, like gently curved acyclic and upholstery. So far I've got an accent chair, sofa (couch), side table, and floor lamp, main focus has been on the accent chair and sofa (couch) Would appreciate any honest feedback on the material contrast, proportions, whether the concept would even be comfortable.
