  • Patent number: 11445830
    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.

  • Publication number: 20200178697
    Abstract: A mattress as disclosed herein comprises first and second pocket coil sections forming the head and foot portions of the mattress, wherein the first and second pocket coil sections are connected to one another by a compressible strip of material extending across the mattress, providing a hinge location for packing the mattress for transportation, in use. This structure allows the mattress to be compressed flat such as by vacuum compression and then folded at the hinge location. The folded compressed mattress can then be rolled up transverse to the folded hinge into a substantially cylindrical shape and boxed for transport. The compressible strip of material, which may be a durable open-cell foam material, allows the mattress to be folded and rolled into a compact form for transport without causing unrecoverable deformation of the mattress springs.
