The present invention concerns a spring core (1, 1a, 12, 13, 17, 18) that may be used in e.g. bed mattresses, chairs or sofas. The spring core (1, 1a, 12, 13, 17, 18) comprises springs placed inside pocket (3). The pockets (3) are placed in a number of rows, which rows of pockets (3) are placed side by side. The spring core (1, 1a, 12, 13, 17, 18) is held in a compressed state by means of at least one cord (5). The at least one cord (5) is formed into braids (6) at opposite outer ends (7) of each row of pockets (3). Further, the at least one cord (4) forms a number of loops (8) on at least one side of each row of pockets (3). By pulling at one free end (10) of the at least one cord (5) the braids (6) and loops (8) are dissolved, allowing the spring core (1) to return to the non-compressed state.

The invention relates to a furniture device (100) for an item of furniture, wherein the furniture device (100) comprises; a frame device (110); a suspension device (130) which is designed to be coupled to the frame device (110); a frame spring device (120) which is designed to cause a first spring effect between the frame device (110) and the suspension device (130); and a suspension spring device (140) which is designed to cause a second spring effect on the suspension device (130).

A resilient unit has strings of individual coil springs (not shown) inside pockets 120 are arranged in an array. The strings together form a spring unit and are each secured to a common cover sheet S, which comprises a non-woven elastic fabric. It is welded ultrasonically or thermally whilst under tension in one or both of its major dimensions—i.e. in-plane—to the pockets 120, the material of which is substantially inelastic and non-woven. In this example the welds, labelled W, are located substantially centrally with respect to the generally circular end surfaces of the pockets.

The present invention relates to a piece of furniture (100) for sitting or lying down on, comprising a frame (110) and a base (130) for a mattress or a seat cushion. The base (130) spans a horizontal surface area and has a thickness which extends in the vertical direction. The base (130) is resiliently coupled with the frame (110). The invention is characterized by the provision of a guide element (150) which ensures that a vertically downwardly directed external force applied to the base (130) results in the base (130) being moved in a guided manner vertically downwards relative to the frame (110).

A support cushion for providing air flow to a user resting on the support cushion is provided. The support cushion includes pocketed coil layer and a base layer positioned adjacent to and below the pocketed coil layer. The pocketed coil layer including a plurality of fabric types for directing air flow. A fan is operably connected to the inlet hole of the base layer to provide air flow into and through the pocketed coil layer to a body support layer. Methods of controlling air flow through a support cushion are also provided.

An adjustable mattress may have an inner spring core between a top and bottom cover. The bottom cover may have at least one section made of a stretchable material that stretches around the mattress as it bends. The stretchable cover reduces the stress on the inner core for the bending when adjusting the mattress. The inner core may be formed from a spring array surrounded by a foam perimeter rail. Sides of the foam perimeter rail may be formed from individual foam coils.

A sleeping system includes a comfortable layer comprising a plurality of pressure relief springs and a supporting layer arranged under the comfortable layer. The supporting layer includes a plurality of supporting springs corresponding to the plurality of pressure relief springs, each of the plurality of supporting springs is connected with one of the plurality of pressure relief springs to constitute a pair of spring, the supporting springs and the supporting springs forms a plurality of pairs of springs arranged along a length direction and a width direction, each pair of spring has a same size, and a ratio of a length of the supporting spring to a length of the pressure relief spring varies smoothly along the length direction of the sleeping system.

A mattress comprising an interior core of inner pocket springs arranged in a plurality of columns extending between opposite ends of the mattress disposed within an exterior periphery of outer pocket springs arranged in a plurality of columns extending between opposite ends of the mattress and a plurality of rows extending between opposite sides of the mattress where each inner pocket spring and each outer pocket spring has substantially the same in pocket height and out of pocket height, and the outer pocket springs are firmer than the inner pocket springs to create a relatively firm border around the periphery of the mattress.

This disclosure addresses mattresses. The mattress includes a core made up of multiple zones. Each of the zones includes a plurality of core elements, the core elements being formed from at least one wire coil spring at least partially contained in a fabric pouch. The core elements are typically joined in linear chains. The zones vary in support firmness according to the selection of a user. The core elements include wire coil springs formed from wires of at least two different sizes, and of at least two different heights.

A cover layer of a fleece material for an innerspring unit comprising a plurality of pocketed springs is manufactured by supplying at least two longitudinal fleece webs, which extend substantially parallel in a longitudinal direction and are spaced from one another, and repeatedly attaching a transverse fleece web, which extends between the longitudinal fleece webs in a direction substantially perpendicular to the longitudinal direction, to the longitudinal fleece webs. The transverse fleece web segments are attached to the longitudinal fleece webs such that they form together with the longitudinal fleece webs a frame-like structure serving as the cover layer.
