Hey Everyone
I want to build a lift up coffee table for my home. You can lift the table up, so you can use it as a desk, and you can open it up, so you can use it as a dining table. So my question is, how can i make sure that when you lift it up and use it as a desk, how can we make sure that the table doesn’t tilt, even when you put alot of weight on the desk. It’s because the weight is not on the center of gravity, so im predicting the table will tilt, so how can i avoid it. 
This video shows how i want it as a desk:
