If you are looking to create a center piece to catch the eye of all at any event or exhibition then it could be worth considering a lighting truss tower. This one shows a large turntable display upon it, it can also carry large Lcd dsiplays or some graphics banners and lighting for illumination of your floor area. This structure was 3445mm high and had a foot print of 800mm sq. A lighting truss tower as this would be raised using, staged legs to make installation and braekdown easy. Then you need to place your display upon the top.
