The invention relates to the field of beds or seats. In particular, the invention relates to a flexible element (10) stiffness that is adjustable stiffness along a compression axis (Z), the element including a compression spring (50). In order to enable the stiffness of the stiffness element (10) to be adjusted, it further comprises both a mechanism (150) coupled to the compression spring (50) so as to be actuated by compression of the compression spring (50) along the compression axis (Z) to move in a direction other than the direction of the compression axis (Z), and also an adjustment device for selectively restricting or releasing the movement of the mechanism (150). The invention also provides a unit (200) comprising a plurality of such flexible elements (10), and a method of adjusting the stiffness of the flexible element (10).

The present invention provides a spring module for a spring cushion of furniture and a spring cushion having the same, the spring module may comprise a spring and a spring bracket for accommodating the conical spring, and the spring bracket may comprise a base, an end cover and a flexible connecting part connected therebetween, the spring may be fixed in the spring bracket with a predetermined initial pressure. The present invention further relates to a spring cushion having the spring module.

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 disclosure relates to a bunk, in particular for a vehicle cabin. The bunk comprises a base plate, an upper layer, a plurality of supporting members vertically compressible and spaced apart from one another substantially over the whole surface of the bunk, a plurality of pressure sensors which are part of the upper layer and in an adaptable area comprising at least one area of the bunk, a moving mechanism configured to move at least some of the supporting members in the adaptable area parallel to the base plate, and a control unit connected to the pressure sensors and the moving mechanism. The control unit is configured to cause the moving mechanism to move the supporting members in the adaptable area as a function of the current pressure data provided by the pressure sensors, to locally change the density of the supporting members to provide a locally variable bunk firmness.
