Question: has anyone tried to move a piano with these?  If so, does it work or will the lifting tool break?
Document: Tried to put pads under a piano. the plastic tip broke the first time I tried lifting. Failed miserably at the piano. I don't see it working for other lifts either. Put it out in the garage to wait for a yard sale.
I've placed caster cups under an upright piano 2 ways: lifting the piano with my bare hands and using this furniture lifter. Using my bare hands, I injured my back and knees and still hurt a week later. With the furniture lifter, I could place the caster cups myself while I lifted the piano with 1 hand. Another nice feature of this set: the soft pads are removable from the plastic sliders, revealing a felt bottom that can be used specifically on hard wood. Anybody who needs to lift and move furniture (that's practically everybody) needs this set.
I figured that way I can move everything in my house without any help from anyone. I highly recommend this product to everyone who has furniture to move. It really is unbeleiveable how well these sliders work & the lifter helped place the sliders under the heaviest items with ease.
The lifting tool and the sliders work fine.A do-it-yourselfer could position:a strip of vinyl floor covering ("slick" side down on carpeting) beneath the heavy items to effect an "easy" slide on carpeting, andsmall rugs (surface side down on vinyl floor covering) beneath the heavy items to effect an "easy" slide on vinyl/tile/linoleum floor covering.
We purchased the "EZ Moves" from Amazon~~~~~~~~The Idea was fine~~~But they don't work !!! When we "TRIED" moving our Log Bed~~~ALL four legs 'easily' slipped off the pads, one at a time. So we tried to move our desk~~~Same result ! !~~~So, we just threw them back in the box !! !Sorry but this was a bad investment~~~They just don't work as advertised !
I have a very heavy hutch made of maple in my kitchen. When I needed to move it the first time, I used a 2x4 and a piece of 2x2 under it for use as a fulcrum and it worked good.I thought maybe this item would work better so I ordered it and it arrived so when it came time to move the hutch back in place I TRIED to use this and it DID NOT WORK.I suspect that the reason I was not able to life the corner with this item is because the small wheel-like fulcrum is too small, and the handle is not the right shape.I tried with all my strength to lift it with this thing and it would not go.
I was able to move my very heavy desk with just the effort of my wife and myself. Only issue was that upon removing the sliders the lifting tool literally flattened out. I had to go get my pry bar to finish the job. Thankfully, no damage was incurred on to the furniture.
Unbelievable!!! Tried lifting our couch with this product & it works exactly as described!!! Wish I had it when we moved into our house in June...all the shifting of furniture around until we got things where we wanted them to sit. So far, no problems using it.
I had seen this product on TV and it seemed like a cool idea so when I knew I was going to need to move a couple of large, heavy pieces of furniture around I ordered this set with the lifting tool. All together the concept worked. I was able to move both pieces, each weighing more than 100 lbs, by myself (at 7 months pregnant). So I am happy and would recommend at this price. That being said, the lifting tool is cheap and I narrowly avoided doing some damage before realizing how careful you have to be while using it.
Saw these advertised on TV a while back and thought they would be very useful. After having new carpet installed in my house I ordered this product and was very pleased with the result. The slides in the kit work well and allow me to move furniture as advertised and the lifting device works well to position the slides under heavy pieces providing enough leverage to do so.
Answer: yes
