These notes clarify how our cart sizing, wheel ratings, and fabric care guidance apply to real shopping situations. Capacity figures assume standard grocery loads, not bulk purchases or oversized items. Wheel durability ratings reflect typical urban surfaces such as paved roads, market floors, and apartment corridors, not rough construction sites or staircases. Fabric care instructions apply to regular washing with mild detergent; heavy stains or industrial cleaning agents may reduce the lifespan of the material.
