We had a similar problem in our house - try this:
We found some plain, smooth metal, nail-in feet, and nailed them to the underside of our sofa - about 1-1/4" diameter. (These are simply to provide some engagement with the rubber floor protectors.)
Then we used largish (about 3-inch diameter) rubber floor protectors - like coasters with a raised lip, and raised rings on the inside surface. I carved out the innermost raised rings, until the best fit to the metal feet was achieved. Lift up each corner of the sofa, and place one of these down on a clean floor.
Sofa does not slide around, and floor is protected - only inconvenience is when you need to move sofa for cleaning - need to re-align rubber protectors.
Hope this helps
