We actually opted to purchase benches, the Chinese ones that look like sawhorses, from a shop on Hollywood almost 10 years ago. They're new, not antique, so they weren't expensive at all. They're beautiful, durable and worth the HK$500/ea I think I spent on a pair of them. When not in use, I place them against a wall to hold plants or as an extra piano/computer bench. I noticed that the stores aren't there anymore as Hollywood has really gentrified in recent years, but you can probably get some in a local furniture store in HK or Shenzhen.
Also, IKEA makes a great folding table which doesn't take up much room when the leaves are dropped down.
