Slipstick furniture sliders make moving furniture easy! Rearranging your furniture or cleaning is simple with our easy-to-use sliders. They can be reused over and over again or can be left under furniture permanently. With a 1,000 pound (450kg) weight capacity per set of four sliders, even the heaviest furniture can be moved, and your floors protected. IMPORTANT: the included 8 plastic sliders are intended for use over carpet and rugs while the included 8 felt sliders are intended for use on hard surfaces. Instructions: Slightly raise or tilt the object to be moved & place a slider under each leg or corner. The black foam side of the slider should face upward. Slipstick furniture sliders are designed for all furniture legs & feet including casters on heavy furniture. Very light furniture may need added weight to stay on sliders.
