It’s a great business-suit sculpt, and while it’s a bit under-detailed when compared to some of the more recent, newer figures, it’s still got a great amount of detail.
For a guy who’s only supposed to sit in a chair all day, he’s got a fair bit of movement. If Professor X could stand, he’d move pretty well. Head, shoulders, elbows, swivel-wrists, torso, hips, ball-jointed knees, and ankles. Granted, you only need half of that if you’re going to stick him in his chair.
