2 Piece Furniture Jack Lift Kit 1. We needed the best lightweight yet strong materials. So we made the movers out of a special kind of strong material. Our cart has 4 sturdy wheels and will support up to 300 lbs, which can support a total of 1200 lbs. 2. Since lifting a heavy furniture leg requires only 1/3 of the weight of the furniture, furniture jacks can be used on 600 lb furniture. The maximum load capacity of 2 furniture jacks (simultaneous use) is 220 lbs. 3. The furniture lifter set is very easy to use and can be used by yourself, regardless of your strength! Use the furniture jack to slightly lift the desired piece of furniture, then place the moving mat sliders underneath and slide your furniture and appliances across the floor with ease! 4. Installing doors, windows and cabinets is an obvious use, but building floors and porches, decks and frames is also a great opportunity to use this ingenious tool. Thanks to the unique structure of the portable jack, all of these functions and more can be easily completed with controlled precision. 5. Furniture trolley wheels are suitable for all kinds of heavy furniture and appliances. Use them for your couch, cabinet, bed, refrigerator, washing machine, bookcase, piano, table, and flowerpot! The sturdy wheels make them easy to glide over any surface, from hardwood floors to carpets.
