Stands for bass traps

I am looking at buying 4 bass traps for each of the corners of my listening room but do not want to screw them into the wall and also want the option of taking them out of the room when company comes. The bass traps are 24" wide and 48" high, does anyone have an idea of what I could sit them on so that they are about 24" off the ground. I need something that is attractive that will pass the wife test

Here is a link to the bass traps I am considering buying (they are local so I could pick them up directly from the factory).
