I have the adjustrite chair. Everyone seems to like it so I bought one. I didn’t take to it right away. It sat in my bedroom for 3 months. Now, it’s at my lever harp. It’s the chair I choose to transport. It folds flat in an instant. It’s a firm seat, nothing too cushiony. I have only sat on it for an hour at a time. I don’t know if anything is comfortable for 3 hours. I like mine okay, I might try it at the pedal harp eventually.
