  • Patent number: 11793320
    Abstract: A pocket spring mattress for use in a bedding or seating product is disclosed. The mattress comprises a plurality of interconnected coil springs enclosed in continuous covers forming strings of pockets accommodating the coil springs. Adjacent coil springs within each string are spaced apart by an interjacent separation distance, said separation distance exceeding at least 20 percent of the diameter of the largest one of the spiral turns of the adjacent coil springs. Further, the pocket spring mattress further comprises a cushioning pad located above the upper end of each coil spring, wherein the covers provides first compartments enclosing the coil springs, and second compartments enclosing the cushioning pads, said first and second compartments being separated from each other. The cushioning pads each have a length extension in the longitudinal direction of the strings exceeding the diameter of the largest one of the spiral turns of the corresponding coil spring.

  • Patent number: 11006764
    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.

  • Patent number: 10624465
    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.

  • Patent number: 10278512
    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.
