What is the difference between a freestanding and a wall-hung storage cabinet?

Freestanding storage cabinets rest on the floor on their own structural base — no wall attachment required (though anti-tip anchoring is recommended for tall units). Wall-hung storage cabinets are mounted directly to the wall structure, with no floor contact — they float above the floor, keeping the floor clear for cleaning and creating a lighter visual appearance. Wall-hung cabinets require solid wall backing (studs or blocking) rated for the cabinet's loaded weight. Freestanding cabinets are more flexible (repositionable) and require no wall modification; wall-hung are permanently fixed but save floor space.
