So I decided to take matters into my own Mommy hands! I cut up cheap nylons to make stretchy bands. I then tied each chair to the leg of the table. The nylons stretch enough that we can still move the chairs to sit at the table, but, much to my children's dismay, the chairs can no longer be moved around the kitchen.
This has saved energy in trying to recollect the chairs for every meal AND saved the frustration of having to maneuver around six chairs scattered around my kitchen! Not to mention that it has stopped that awful grating sound of chairs being scraped across the floor!
