    Pretty cool--how'd he do it?

    My guess is a heavily weighted column, or possibly there are some fasteners which go into the floor, though that would make moving the table a little difficult.

    My guess is a heavily weighted column, or possibly there are some fasteners which go into the floor, though that would make moving the table a little difficult.

    with the amount of leverage, the column would have to have a huge weight, almost impossibly too huge.
    Assuming the base is about 1 ft diameter and the table center to edge is about 4 ft, the base would have to weigh about 1600 lbs to keep a 200 lb guy leaning on the table edge to keep if from falling over, not to mention books, computers etc on the table.

    It has to be bolted to the floor.
    in my book, removing some bolts can't be much more difficult than moving a 1600 lb table.

      Perhaps there's support under the table connected to the column that's out of sight to assist with the weight of the top. Still, I'd have to agree with Loring about the bolts.

        Hot melt glue, or maybe Velcro.

          We have a 20- or 22-foot board-room table made of 5"-thick butcher-block-laminated hardwood (we're a forest products company) and it is supported by a single 24" steel-reinforced-concrete pillar. It's part of the building, does not move.

          Once the CEO pounded his fist down hard on the head of the table an spilled a couple of coffees on the far end. Other than that, it's pretty darn solid.

            That's neat but where would I hide all my junk?

              It's possible that the column is heavy. It could be filled with lead. Actually it could be moved by tipping it and rolling it on edge, by a couple of very big, brave guys. But, the trick to this table might be that we don't know for sure what the top is made out of. It could be very light. It appears to be glass or something heavily lacquered. The column does appear to go through the top.

                The specification says that the leg can be placed anywhere underneath the desk. I bet that the top of the column is packed with rare-earth magnets to clamp the desktop against the column base.

                  The column could be filled with water after it's moved but prior to putting the top on. That would be enough weight, I'd think.

                    My first thoughts were along those lines. The part of the leg that appears to stick out of the top of the table could actually be the mate of the magnet in the leg. That could hold the top wherever it's positioned. Bolts on the bottom of the leg would give it the mechanical stability.

                      I too had the same thought about the magnets after reading the part about the leg being able to be placed anywhere. There's clearly SOME reason for that small, dome-like piece on top. Being able to place the leg anywhere means the two pieces aren't fastened together mechanically, and it's too small to weigh very much, so magnets is about all that's left.

                      If the table is considered a display-only piece, i.e. like a piece of sculpture, the base might be heavy enough to balance the weight of the top without being bolted down. Otherwise, I agree with Loring ... the leg probably can't weigh enough to counteract the leverage of someone pushing down on the table's far end. Further, such a heavy weight would far exceed what any kind of standard building construction can safely support.
