Really great product. Does everything advertised and more. not only makes PU furniture and other PU leather items new and protected, but also makes PU leather more like real leather. I used it on a small sofa and an office chair and was amazed at the result. They both look like they've gone up a lot in price because it's hard to believe they're faux leather furniture anymore. It doesn't leave stains, isn't greasy and isn't artificial. TriNova absorbs directly into the artificial leather and leaves no residue after gentle polishing after the required drying time. Faux leather is softer and more resilient, and I've used it on brand new things. I'm sure it will work wonders with old stuff. Definitely a must have in any home or office with faux leather furniture. PS I just bought the TriNova Leather Cleaner and Protector!
