Review on 🚚 Ultimate Heavy Duty Furniture Lifter: 660 lbs Load Capacity, Adjustable Height + Appliance Roller Sliders for Easy Moving of Sofas, Refrigerators & More by Ryan Turner

A very small piece of paper just shows all the parts and doesn't explain how to use them. After several attempts to move the sofa from one room to another, I figured out how to adjust the height of the handle and raise it to allow a slider (the plastic slider I ordered with the orange stuff) to go under the sofa leg came. Casters are useless for carpet floors. Works great with large sliders to slide sofa onto carpet. I'm not sure how and when to use the black round objects other than to add height to the handle to lift the sofa/chair etc to put a plastic disc underneath. Couldn't figure out why I needed 4 of these with only 1 lid that fit on the handle. Should this black piece fit on the yellow rollers? Need a picture of how things should be used together. Rather confusing.
