The faux leather material on the seat immediately wrinkled. But that's not such a big problem. The issue is that within 5-6 months of regular use (a few hours, some days), the seat has become completely flat, like sitting on plain wood. As a natural consequence, after 5-10 minutes, you start feeling uncomfortable and want to get up. I do not recommend it. It goes without saying, of course, that they don't offer any warranty...
