Mattress assembly with a mattress topper that includes pocketed coil springs and methods of producing the same

A method of producing a mattress topper for connection to a mattress core, comprising the steps of:

• providing an array of coil springs;
• positioning the array of coil springs between an upper fabric layer and a lower fabric layer;
• connecting the lower fabric layer to the upper fabric layer between each coil spring with a plurality of overlapping welds;
• connecting a backing layer to said lower fabric layer by said plurality of overlapping welds;
• connecting a padded layer to said upper fabric layer by the plurality of overlapping welds;
• connecting the textile layer to the padded layer by said plurality of overlapping welds.

A mattress topper, comprising:

• a plurality of coil springs,
• an upper fabric layer extending above the plurality of coil springs, and
• a lower fabric layer extending below the plurality of coil springs and connected to the upper fabric layer by an overlapping weld around each coil spring of said plurality of coil springs such that the upper fabric layer and the lower fabric layer collectively form a fabric pocket encasing each of said coil spring;
• a padded layer positioned atop the upper fabric layer, said padded layer comprising a visco-elastic foam, or a fibrous material, or both a visco-elastic foam and a fibrous material;
• a textile layer positioned atop the padded layer;
• and
• a backing layer positioned below the lower fabric layer,
• wherein said upper fabric layer is connected to the lower fabric layer by said overlapping welds, said backing layer is connected to said lower fabric layer by said overlapping welds, said padded layer is connected to said upper fabric layer by the overlapping welds, and the textile layer is connected to the padded layer by said overlapping welds.
