Thanks Arthur. Actually I made it. The maple platforms are from Timbernation, the supports are from a hardware store, and the table sits on Ken Lyon's neuance platform. The springs are left over from a Promethean Base that I was using at my last house when I had the table set up on a rack on a sprung floor. It wasn't my intention to use them again, since my floors are carpet over concrete slab, and the table is wall mounted now. But they did make a noticeable improvement, so use them I did.
