I love my Martelli's, but previously I bought a dining room table from the closeout section and used that one on risers. Check out this website I found with all sorts of ideas:

Here is something else I found:

I don't know if you can access the website, but it's Home Depot, Martha Stewart Craft Space table. It does collapse.
