Moving men as at http://www.storeshop.com/furniture_sliders.html rely om a very smooth surface cutting down friction against carpet.

The results are actually pretty impressive.

You are right. The makers have responded to demand by producing:

hard surface Moving men which adds heavy gauge felt pads specially equipped for gliding on hard smooth floor surface including hard wood floor.

You need to buy a bumper pack of moving men to get your hands on these and "bumper" bumps up the initial cost :)

We have been suggesting using a run of carpet or carpet offcut as temporary tracks to go under the regular moving men so the furniture can move out enough to clean under.

Let us know if you try the product.
