To all,

Many thanks for the tips and web-site links.

To sumarise,
- for sofas, use non-marking gray rubber castors (the sofas have to be
mobile, to be able to vacuum-clean behind them)
- for the grand piano, use castor cups, it doesn't have to be so mobile

Regards,
Paul

For the piano, I don't know what to do, any ideas?

You could try castor cups but probably the only thing that'll work is
replacing the tiny brass castors with a proper A-frame support with
decent sized rubberised wheels. This is more the kind of thing you'd see
at a concert hall or school, of course. Reduces the strain on the
spindly legs when you push it around, as well.

Downside: it doesn't look as good and the piano will end up somewhat
higher.

Ask at a piano shop, or look at this page:
