The shoulder dolly is definitely a bonus when moving heavy furniture. The problem is moving up and down stairs. It was on the verge of being dangerous moving heavy objects up or down the stairs because there is not enough clearance for your legs. Therefore, the person higher up on the stairs has to straddle the object being carried which is difficult since there isn't much room to do so. We tried lifting the objects higher, but the person lower on the stairs then has a face full of furniture and really has to hold it with their head!But on flat ground, this dolly was a life saver.
