Ugh, moving heavy furniture alone is the worst, right? These Hasware furniture sliders are little lifesavers. You get four of them, each about 50x50mm (that's roughly 2x2 inches). They're made from EVA and PE felt material – one side is soft felt, the other is a slick black surface. You place the black side down on your hardwood, laminate, tile, or linoleum floor, and the felt side goes under the furniture leg. Then you can just glide that couch, dresser, or bed across the room without scratching your floors or killing your back! They're reusable and durable. Seriously, for cleaning, rearranging, or moving day, these are a must-have. Just make sure you put one under each leg or corner. Makes a huge difference. Save your floors and your spine!
