Remember those non-slip drawer liners you bought on a whim? They’re about to become sofa heroes. Cut a strip of that grippy, open-mesh stuff and lay it under your cushion.
It’s basically gecko feet for your couch. The cushion grabs it, the sofa base grabs it, and nobody moves. Cost? About three bucks. Victory? Priceless.
Quirky fact: This same material is used to keep yoga mats from sliding. Your sofa is now basically doing an awkward downward dog. Namaste, floor cushions.
