Ours are very heavy, and the bases do not move at all during travel. The rocking feature, however, does move, and would bang up against the wall. So, I found a hole in the stationary part of the base, put a 5/16" bolt in it, and it keeps the rocker from moving. Then just remove the bolt when we get to the CG, and all is well again.
