I agree with the previous speaker's answer. We dared to mount a table top of 200 x 100 cm on it. This is not as stable as another, heavier lift table frame. Nevertheless, you can work well on it.
No. Some of us in the shop have this table. We are very satisfied. There are other models (we also use them) that are not nearly as convincing. From our point of view, it's a very good frame.
