Patent ID: 8438681

Claim:
A furniture device adapted to receive the weight of a being, the furniture device comprising at least one section, wherein the section comprising: a fundament adapted to be in connection with the ground; a plate member provided above the fundament with respect to the ground; a first set of elastic members arranged beside each other on the plate member and connected to each other by means of an array of connections, each elastic member comprising a length defined by an upper end and a lower end, and being adapted to be elastically deformed along said length when loaded with the weight of the being and to act on the being with a force that depends on said elastic deformation; a plurality of connection members connecting the elastic members at the array of connections between the first set of elastic members to the fundament, and extending through the plate member, thereby attaching the first set of elastic members to the fundament; and a deformation member adapted to displace the plate member in relation to the fundament; and thereby variably deforming the elastic members; wherein each elastic member comprises an elastic element having a first spring constant and a flexible envelope that encloses the elastic element so that the elastic element is clamped within the envelope, said connections being located between the upper and lower ends of the elastic members, said connection dividing each of said elastic members between an upper part with an upper length extending between the upper ends of the elastic members and the connections, and a lower part with a lower length extending between the connections and the lower ends of the elastic members, wherein said upper length is mainly unaffected by the displacement of the plate member and said lower length is adjustable by means of the displacement of the plate member.
