Steinway concert grand casters

[Horace Greeley]

Wally Brooks used to demonstrate this kind of coupling (at convention 
classes) by slipping a small piece of 3/8" soundboard spruce between the 
caster and carpet in whichever room he happened to be teaching.  The 
results were quite striking and convinced a good many skeptics.

As Dan notes, it does not take much to restore the connection you want 
through bypassing the one that you do not.

Best.

Horace
