  • 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.
