Abstract: The invention provides a single piece tension-varying slider for a set of three slats of a bed base, which set comprises two parallel slats in the plane on which the mattress rests and a lower slat disposed substantially in the vertical midplane between the two upper slats, said slats being supported at their ends by fixing means for fixing to the longitudinally-extending members of the frame of the bed base, said slider comprising a suspension device for bearing against the lower slat, and fixing means for fixing said device to the upper slats, wherein the fixing means comprise a strip for being placed across and over the upper slats, said strip having a respective bend at each of its ends for co-operating with a respective outer edge of said two upper slats, one of the bends being connected to the suspension device by a junction wall.

Abstract: The invention provides a device for suspending slats of a bed base, the device being constituted by a one-piece unit presenting a top section having two housings for receiving the ends of two parallel slats, a bottom section provided with anchor means to anchor said unit to a bed frame, and an intermediate section connecting the top section to the bottom section and constituting the resilient suspension element, said bottom section having a vertical bottom wall for bearing against an inside face of said frame and a horizontal top wall for resting on the top face of said frame, and said unit presenting a vertical plane of symmetry perpendicular to said top wall and to said bottom wall, wherein the intermediate section is constituted by semicylindrical wall portions that are substantially bodies of revolution about axes perpendicular to the plane of symmetry, said wall portions connecting the top section to the bottom section, and said axes of revolution being disposed inside the volume defined by said top sect
