Table top is four 50-pound bags of ready-mix grout concrete (no stone, just sand), 3m of 1m wide 1x2inch fence mesh.
Chairs were solid white upholstery. We bought them in a second-hand store and painted with diluted acrylic (to hide old stains). Waiting 30 days before I apply sealer to the concrete.
top slab is about 230 or 240 pounds. Wood base is only about 15 or so; light. I made no attachment between the concrete and the wood - just gravity.
