  "abstract": "A grid framework structure, configured to support one or more load handling devices, includes: a first set of grid members extending in a first direction and a second set of grid members extending in a second direction, to form a grid structure having grid cells. A plurality of vertical uprights create a storage space for storing containers in a stack such that load handling devices operative on the grid structure can lift containers through a grid cell from a stack below the grid structure. The vertical uprights are arranged such that a section of the grid structure including four adjoined grid cells is supported by five or fewer vertical uprights.",
