I recently moved my granny's, and it was also essential for me to find a company that won't only move everything in one go, but also that the furniture wouldn't damage on the way. We contacted
https://loparemovals.com/european-removals-switzerland as we chose them by the reviews and didn't regret it at all. The whole process was well organized. The movers loaded all the things pretty fast, we wouldn't have made it if it wasn't for the guys. They delivered all the boxes in perfect order, no damage. And this was very important, since my granny had a collection of glass items.
