A plurality of elongate springs are provided and extend in a flat or curved plane, the ends of each elongate spring being attached to one of the at least one non-elastic flexible elongate elements at two separated connections.

Abstract: A pocket spring mattress arrangement, such as a bed arrangement, having adjustable firmness is disclosed. The mattress arrangement includes a pocket spring mattress having a plurality of pocketed units of coil springs individually arranged in pockets formed of a casing material. The mattress has at least two parts of which at least one is a compactable part. Further, at least one elongate actuation member extends perpendicular to a compacting direction for the compactable part(s), corresponding to a width or length direction of the mattress, and is embedded within the mattress between two of the parts. The actuation member is moveable in the compacting direction to expand or contract at least one of the one or more compactable part(s) of the mattress. Elastic elements may further be provided to contract one or more of the compactable parts.

Abstract: An individually pocketed coil spring for use in a bedding or seating product, is disclosed, as well as pocket spring mattresses including such pocketed coil springs. The individually pocketed coil spring include: a coil spring having an upper end and a lower end; a casing forming a pocket enclosing said coil spring; and a cushioning pad located above said upper end of the coil spring. The casing provides a first compartment enclosing the coil spring, and a second compartment enclosing the cushioning pad. The first and second compartments are separated from each other.

Abstract: A spring mattress is disclosed, comprising a plurality of interconnected coil springs enclosed in casings, thereby forming a pocket spring mattress. For at least one of the springs, the casing portions arranged at the ends of the spring being moved towards each other, through the spring, and interconnected with the aid of connecting means, such as a weld. Further, the casing portions at the ends of the spring comprise an opening through the spring. Hereby, the casing forms a toroid or doughnut shape enclosing the spring.

Abstract: A mattress arrangement, such as a bed arrangement (1), having adjustable firmness is disclosed. The mattress arrangement comprises an upper mattress (3) and a lower mattress (4) being arranged beneath said upper mattress (3). At least one side (41) of the lower mattress (4) is moveable in relation to an opposite side (42) of the lower mattress (4), the lower mattress (4) thereby being expandable into an expanded state, having a lower firmness, and compressible into a contracted state, having a higher firmness. A support layer (6) is arranged between the upper mattress (3) and the lower mattress (4), to partly support the upper mattress (3), and arranged overlying the at least one moveable side (41) of the lower mattress (4). Hereby, at least one compartment is formed beneath the upper mattress (3), wherein the compartment(s) is at least partly empty when the lower mattress (4) is in the contracted state and at least partly filled when the lower mattress (4) is in the expanded state.

Abstract: A mattress arrangement, such as a bed arrangement, is disclosed, comprising an upper mattress and optionally an lower mattress. The mattresses are preferably pocket spring mattresses. A support structure is arranged beneath the upper mattress, and comprises at least one flexible elongate element arranged to extend between two holding elements arranged at opposite sides of at least one variable zone in the bed arrangement. A retraction device is further arranged to control the slack of said flexible elongate element(s) by controlling the length of the flexible elongate element(s) being provided between the holding elements. Hereby, the height and/or firmness of the bed arrangement is controlled in the variable zone(s).

Abstract: A bed arrangement including adaptive properties is disclosed. The bed arrangement includes a mattress including at least one zone including independently adjustable firmness and/or height, a drive unit arranged to adjust the firmness and/or height of the at least one zone and at least one sensor. The sensor(s) is adapted to measure a physical parameter which is relatable to a lying position used by a user. Further, a control unit is arranged to determine, based on input from the sensor(s), the present lying position of a user. The lying position is determinable to be one of a set of at least two predefined lying positions. Further, the control unit controls the drive unit to adjust the firmness and/or height of the zone(s) to preset firmness/height value(s) corresponding to the determined lying position. Hereby, an automatic adaption of the bed properties to various lying positions is obtained.
