Hi...thank you for the quick response. It is dark brown faux leather. I think bicast / bycast leather. I was told it was leather when I bought it 5 years ago and it was expensive, so I never thought twice about it until recently. The store has since gone out of business, so I can't find out exactly what it is and no tag...but pretty certain it is bycast after looking online.

My apartment gets hot during the summer when I am at work with lots of direct light and I think the coating couldn't take it. Just recently it started getting really sticky. One section is really rough and sticks to clothes now. I used some leather conditioner and some random cleaners and it just made it worse. I know now that was dumb.

Hopefully it is fixable! Looking forward to hearing what the solution is.

Chris
