  • the suspension is therefore referred to as a suspension.
  • the slatted base has a plurality of spaced apart parallel juxtaposed carrier profiles, in holztener execution also referred to as slats.
  • the support profiles are usually connected by support body with longitudinal members of a rectangular frame, which is part of the spring base.
  • the carrier profiles extend transversely to the longitudinal beams, may have different cross-sections and be made of a variety of materials. When pressure is applied to the upholstery, the carrier profiles yield elastically or bend resiliently.
  • a suspension is from the document DE 3 718 285 A1 known.
