Unless you're the Incredible Hulk, moving heavy furniture across carpet is a difficult, back-straining process. Make the process a little easier with a bit of aluminium foil.While you can always grab furniture sliders to move that big furniture, a bit of aluminium foil should help serve the same purpose. Just stick it under the furniture's legs (shiny side up; the dull side is actually more slippery) and it should drag across the carpet much easier. It'll still be heavy, of course, but you won't have as much trouble getting it started, and it won't "jump" around as much when you drag it.
