Hi, I want to make a really narrow table to sit behind the sofa. Similar to the image below. It would just be for drinks etc. Needs to be about 90cm high, 300cm wide and I'm thinking about 20cm deep. I don't have many tools and live in an apartment, so looking for a design with minimal construction required! I was thinking of using a couple of lengths of pine for the top and 2-3 90cm pieces as 'legs'. It doesn't need to be free standing as it will be wedged between the sofa and the wall. I could possibly wall mount it too (although the walls are concrete so I'd rather not!).

As it needs to be fairly long, looking for ideas on the best way to join the 'top' pieces. Any other advice also welcome! Thanks in advance.
