Tables

I'm looking for a table for chess study, I could place it next to my desk or use it while sitting on the sofa with a book. I have a standard tournament vinyl roll up board that is 20x20 with plastic pieces. I'm a student and I live in a studio apartment. I was thinking a small folding card table or even a folding child's table would convenient. My desk is 29". I don't need any extra space to speak of on the table. Has any else tried this? What height do you think would be comfortable? 

No one replied to this topic, but in case you are curious, I went ahead and ordered a children's folding table. It is 21 inches tall and 24x24. It could not fit my chessboard more perfectly. It is also the perfect height when sitting at my desk reading a chess book. The one I ordered is made by Lifetime and extremely sturdy.
