Abstract

A mattress includes an outer casing, and an inner core that is surrounded by the outer casing. The mattress has two major faces, two long side faces, and two end faces. The inner core includes a plurality of pocket springs that each have at least one spring within a fabric pocket. Each spring is compressible along a compressive axis, and the pocket springs are arranged within the core such that the compressive axes extend perpendicularly to the two major faces. The pocket springs are arranged into two lateral sets, and a central set. In each lateral set, the fabric pockets of adjacent pocket springs are interconnected in regions adjacent the major faces of the mattress. In the central set, the fabric pockets of adjacent pocket springs are interconnected in regions adjacent the major faces of the mattress. The central set is disposed between the two lateral sets, and extends in a direction parallel to the long side faces of the mattress. The central set is joined directly or indirectly to each of the two lateral sets by first connections that are disposed substantially centrally between the two major faces, such that springs in each lateral set are compressible independently of the springs in the other lateral set.

Dependent claims

A mattress comprising an outer casing, and an inner core that is surrounded by the outer casing, the mattress having two major faces, two long side faces, and two end faces, the core including a plurality of pocket springs that each comprise at least one spring within a fabric pocket, each spring being compressible along a compressive axis, and the pocket springs being arranged within the core such that the compressive axes extend perpendicularly to the two major faces,

wherein the pocket springs are arranged into:
two lateral sets, wherein in each lateral set the fabric pockets of adjacent pocket springs are interconnected in regions adjacent the major faces of the mattress;
and
a central set, wherein the fabric pockets of adjacent pocket springs in the central set are interconnected in regions adjacent the major faces of the mattress, the central set being disposed between the two lateral sets, and extending in a direction parallel to the long side faces of the mattress;
and wherein the central set is joined to each of the two lateral sets by first connections that are disposed midway between the two major faces, such that the pocket springs in each lateral set are compressible independently of the pocket springs in the other lateral set;
and wherein the core further includes at least two elongate flexible strips,
wherein each elongate flexible strip extends between the central set and a respective one of the lateral sets,
wherein each of the first connections connects the fabric pockets of the central set with a respective one of the elongate flexible strips,
and wherein each elongate flexible strip is joined to the respective lateral set by second connections that are formed in a region adjacent at least one of the major faces of the mattress.

wherein the pocket springs are arranged into:
two lateral sets, wherein in each lateral set the fabric pockets of adjacent pocket springs are interconnected in regions within the core adjacent the major faces of the mattress;
and
a central set, wherein the fabric pockets of adjacent pocket springs in the central set are interconnected in regions within the core adjacent the major faces of the mattress, the central set being disposed between the two lateral sets, and extending in a direction parallel to the long side faces of the mattress;
and wherein the central set is joined to each of the two lateral sets by first connections that are spaced from the or each sleeping face and wherein the central set is not connected to either lateral set in a region within the core adjacent the or each sleeping face,
and wherein the core further includes at least two elongate flexible strips,
wherein each elongate flexible strip extends between the central set and a respective one of the lateral sets,
wherein each of the first connections connects the fabric pockets of the central set with a respective one of the elongate flexible strips,
and wherein each elongate flexible strip is joined to the respective lateral set by second connections that are formed in a region adjacent at least one of the major faces of the mattress.
