I purchased 2 of these a little over a year ago.  The chairs are very sturdy, which I like, but after noticing some color on back of my shorts after sitting in them recently, I wiped them down with a gentle microfiber towel dipped in a dawn dish detergent/water mix thinking maybe the chair was dirty.  When drying the chair off, I realized the color was coming off.  I only used a little soap/water, so nothing harsh and I kept them covered during winter under waterproof chair covers under a patio cover during winter. I only noticed it because I was wearing light colored shorts.  Although I like how these chairs feel, I can't have people use them knowing the color will stain their clothes. Really disappointing something like this is happening.  I see from other reviews, it's not just me either.
