Abstract: A firmness controlling apparatus for use in a bed arrangement or a seating arrangement is disclosed. The apparatus comprises a rigid frame having two opposed sides, and at least one non-elastic flexible elongate element extending between the two opposed sides. Each end of the non-elastic flexible elongate element is directly or indirectly connected to one of the opposed sides, and at least one of the ends is indirectly connected via an elastic flexible elongate element. 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: 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 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 spring mattress is disclosed including a plurality of strings interconnected side by side, each string including a plurality of continuous casings and each casing including a coil spring. Further, in at least one embodiment, at least one of the casings in at least one of the strings includes a plurality of stretch openings into the interior of the casing, wherein at least some of said stretch openings are displaced in relation to each other in a lengthwise direction of the spring. At least one embodiment of the present invention also relates to a method and a device for manufacturing of such a mattress, as well as to a bed adapted for such a mattress.

Abstract: A spring mattress is described, including a plurality of strings interconnected side by side. Each string includes a plurality of continuous casings and, enclosed therein, coil springs. Moreover, between at least some of the springs in at least one of the strings a slot is arranged which opens towards the upper or lower side of the mattress. It is preferred for the springs between which the slot is arranged to be separated with an intermediate separation distance, which separation distance exceeds about 10% of the diameter of the largest turn of the adjoining springs. In addition, it is preferred for the casing portions to be arranged at the ends of the spring to be moved towards each other, through the spring, and connected to each other by at least one connecting device.
