ABSTRACT:
The invention provides a top plate for a unitary suspension device for a multi-element type bed base made with a plurality of unitary suspension devices disposed in rows and columns on a support platform, the top plate being quadrangular in shape and including in its central region fastener members for fastening to the top end of a suspension structure of a unitary device, wherein the corners of the top face of the plate are raised and define a horizontal plane situated above the face, and wherein the top plate presents around its central region a first convex surface forming a dome. Advantageously, the top face of the top plate presents in the vicinity of each of its corners a second convex surface tangential to the horizontal plane and connected to the dome via demarcation lines.
