Saturn's mean density is lighter than water. It's a relatively 'fluid' planet.
Is it gaseous all the way down? If not is there any sort of boundary between dense gas/liquid or solid?
Due to the pressures, I assume it has a 'solid' core, and even the gasses in the middle layers are probably very viscous. But I don't know the density threholds at various levels.
None of the planets are really solid all the way down. Most are fluid to some degree or another. Even Earth is molten rock and metal most of the way down. Then we have a thin layer of crust and a thin layer of atmosphere.
Saturn is probably more like a big thick atmosphere surrounding a kernel of relatively solid compressed gas.
