I do not like this product at all. It is very flimsy plastic, does not stand up by itself when folded (must be wedged in between two things to stay up), and sags when you put any weight on it. Then there is the cup holder that will not hold a cup. Two out of the four trays I got, the cup holder broke the first use. With the slightest bump the table top can become unhinged and your stuff with fall everywhere. The only good thing I liked about this is the adjustability. It can adjust up or down and at an angle. That being said.....Do NOT buy this. Save yourself the headache.
