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).
A flexible element for a piece of furniture for lying or sitting on, the element having stiffness that is adjustable along a compression axis and comprising:
A method of adjusting the stiffness along a compression axis of a flexible element for a piece of furniture for lying or sitting on, the element comprising a compression spring and a mechanism coupled to the compression spring so as to be actuated by compression of the compression spring along the compression axis in order to move in a direction other than the direction of the compression axis, the method comprising a step of:
