An upholstery spring comprises a steel spring wire made of a microalloyed steel and a color indicator arranged thereon at least in some regions, the microalloyed steel containing between 0.004 to 0.015 wt.-% of one or more alloy elements. The invention further relates to a method for producing an upholstery spring, a mattress or a piece of upholstered furniture having such an upholstery spring.

Mattress assemblies include a hybrid posture support system that provide an end user with improved posture support during use, among other advantages. The hybrid posture support system includes a top foam layer including first and second foam portions that are spaced apart and generally correspond to a head/shoulder region and a foot region, respectively, a pocketed microcoil array underlying the top foam layer that is intermediate the first and second foam portions; and an underlying foam layer. The hybrid posture support system can be used in any mattress assembly including mattresses having a coil spring innercore or a foam innercore.

The present invention relates to beds having a support surface defined by a plurality of support members (104, 204, 240). According to some aspects the support members are sprung (104, 204) and the bed includes a damping system (106, 206), for example a damping arm (124), for damping vibrations of the springs (118, 218). According to some aspects the support members (204, 240) have laterally extending pusher members (236, 238) arranged to engage with adjacent support members (204, 240); the pusher members (236, 238) comprising damping material (254). According to some aspects the support members (104, 204) are received by a guide member (320, 420) made up of two parts (320a, 320b, 420a, 420b) arranged to retain a spring by engaging between the coils of the spring (418). The present invention also relates to bed frames comprising a plurality of movable side elements (568, 768, 1068) mounted for movement in a direction substantially normal to the body support surface. The side elements (568, 768, 1068) are resiliently urged towards an unloaded position. The present invention also relates to methods of manufacturing beds.

The present disclosure relates to the field of elastic pads and discloses an elastic pad, an assembling method thereof and a furniture. An elastic pad includes a first elastic module mounting part, a plurality of first elastic modules disposed on the first elastic module mounting part in a predetermined arrangement, and a pad layer on the plurality of first elastic modules. An outer edge of the pad layer and an outer edge of the first elastic module mounting part are connected via a releasable first connection structure, leaving the sides of the elastic pad open or uncovered. The elastic pad has fewer components, a simple structure, lower cost, and improved comfort. Since the first connection structure is releasable, the pad layer can be disassembled, which facilitates assembling and transportation of the elastic pad and reduces required storage space.

The invention relates to the field of furnishing. In particular, the invention relates to a stiffness adjustment device movable between an interference position for imposing a restriction on the deformation of a seat, back or bedding spring, and a non-interference position for releasing the spring from the restriction. The stiffness adjustment device comprises a resilient element, e.g. such as a flexible blade and, as it moves between the interference and non-interference positions it passes through an intermediate position in which the resilient element is subjected to resilient bending that is greater than in the interference and non-interference positions.

A spring bed is provided for supporting the lumbar (lower back) curve, which provides a continuous contact on the lumbar region by preventing the lumbar curvature (hollowed space) which occurs due to the cavitation caused by the pressure on the user's buttock part on the bed. The spring bed has lower springs arranged side by side so as to take the shape of the lumbar curve on the spring bed and upper springs arranged side by side which take place on the lower springs.

A complex spring unit (10) comprises at least a first spring portion (12) and a second spring portion (14), which first and second spring portions are integrally formed, wherein the first spring portion is arranged in use to be placed under compression, and the second spring portion is arranged in use to be placed under tension, during compression of the complex spring unit.

A furniture device configured to receive the weight of a being, said furniture device comprising a holding arrangement (20, 120) and at least one section (30, 30,130) comprising a base (2, 102), a movable plate element (4, 104), a moving mechanism (6, 10) and at least one elastic device (12, 112). The plate element (4, 104) is configured to interact with the at least one elastic device and to be moved by the moving mechanism in respect to the base in order to adjust the firmness of the at least one elastic device. The elastic device comprises a pocket (14, 114) made of a flexible sheet material, and an elastic member (18, 118). The holding arrangement comprises a holding member (22, 122), which is fixed in relation to the base (2, 102) or the plate element (4, 104) and a connecting portion (24, 24,124) which is arranged at the elastic device (12, 112) and which connects the holding member to the elastic member. The elastic member (18, 118) exhibits a first portion (18a, 118a) arranged proximal to the free end of the elastic member, a second portion (18b, 118b) being arranged distal to the free end of the elastic member and an intermediate portion (18c, 118c) arranged between the first and second portions. The holding member (22, 122) is, via the connecting portion (24, 24,124), connected to the intermediate portion (18c, 118c) of the elastic member, such that, during movement of the plate element (4, 104) relative to the base (2, 102), the elastic member (18, 118) is compressed and relaxed only over the second portion (18b, 118b).

The present invention concerns a spring core (1, la, 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.
