We have our clever tables on the stand, and are more than happy to show you how they work. At the show we are probably opening and closing each of them 200 times a day. By the time the show finishes, they will have well exceeded their usual lifetime of use! So it may be a lot of times, but its a great way of showing you how excellently sturdy and hardwearing our tables really are! Plus we love opening and closing them, so to us its a whole lot of fun!
