Hire a carpenter to build new ones.
Some pine 1"×6" or pallet wood and linseed oil you can even cut some designs in them

I answered on your other question about this. I would think about painting them and adding carpet stair treads. https://www.google.com/search?q=carpet+for+stair+treads&rlz=1C1CHZL_enUS718US718&oq=carpet+for+stair&aqs=chrome.3.0j69i57j0l4.6806j0j8&sourceid=chrome&ie=UTF-8
Paint or stain them.
Add risers, then a stain to make them the same tone and add a finish coat.
Paint them with a nice chalk paint
get some batting and fabric and upholster them after you paint or stain the frame to match your decor.
