If the seat is not stable and shaking, maybe is the clamps that go under the seat were too big and do not fit great with the seat tube, so the clamps could not be tightened.
You can using a micro fiber cloth and tightly wrapping the seat tube around, then attach the clamp and tighten. This time the clamps could be tightened.
