Sure, lots of mice, ok, most mice can be coddled to work on fabric. But it takes a company with a dedicated mousing portfolio the size of Logitech's to design a mouse specifically for use on the sofa.

That means it won't collect bits of fuzz around the sensor when dragging it across the couch, bed, or a trouser-clad thigh.
