"Wanted dolly to move piano but no furniture dolly available for next day delivery. So got these instead. I had checked weight of piano on internet - 365kg. So in theory these were ok - 400kg. That night assembled dollies in few minutes. Put carpet on dollies and in no time piano in new room - and no muscle strains."
"These are described as wheel dollies for moving cars - however, I bought them for moving other bulky items (not as heavy as cars). They seem well made and move easily. However, the first one I received only had half the number of bolts needed to assemble. Screwfix dealt with this quickly - they sent me another pair for me to remove the required bolts!"
