Abstract
A mattress spring core including a sheet and a plurality of spring core units arranged on the sheet. The spring core units are arranged in longitudinal strings, the strings being attached to the sheet side by side to form a rectangular shaped mattress spring core. The sheet is configured to stabilize the rectangular shape of the mattress spring core by preventing the spring core units of a first string to be displaced relative the spring core units of an adjacent string.
