The chromium plating on my Co Chair has held up beautifully after months of daily use, no scratches or dulling at all. It's just a thin electroplated layer, but it gives the metal a mirror-like shine that still looks new.
Wasn't sure how a thin chromium plating would hold up, but six months in and the finish still looks brand new. Wipes clean with a damp cloth, no dulling or water spots like the bare metal table I had before.
The chromium layer gives this chair's frame a mirror-bright look that hasn't dulled after a month of daily use, and it wipes clean with just a dry cloth. I was worried about thin plating, but the finish feels substantial and smooth to the touch.
