Weeble-Wobble

I am planning the home for my upcoming egg. How stable is the XL egg sitting on a good solid flat surface without side support. Example: sitting in a built in kitchen without a "hole" in the counter--open front style. I dont plan on moving it once it is in place. There will be no wheeling it down the sidewalk. My neighbors can come over i will gladly feed them here. BUT, have you ever had it tip--at all. I do have fairly active boys but they are not super destructive types. I do not want to buy the nest just for the time period it takes to finish the kitchen. I can easily put a table together. I was going to simply put it on some stacked pavers in the corner so i can use it while the kitchen is finished. Thoughts?
