  • Spring mattress
    Patent number: 4662011
    Abstract: The invention relates to a spring mattress of which the body is formed by spaced apart rows of springs connected by elastically deformable members. The latter enable the body to bend along transverse lines of break located between the rows of springs, with the result that the mattress is so flexible as to be adapted for use on an articulated bedstead or slatted framework.
