After 4 years of full time I haven't found the need for any stabilizers. I am alone most of the time so any movement is caused by me which I don't feel anyway. I have gotten used to the movement caused the Splendide washer/dryer combo and can even sleep while it is running in the same room. Now when I do have company they don't seem to mind the movement either or they are just too polite to mention it. Either way, I'm happy as is.
