The spring bridge (2) includes a main, load-bearing bridge (6), which can be fitted in the frame of a mattress base, and one or more supporting elements (8) arranged thereon. The supporting elements (8) extend, preferably in the form of a sheet-like, wing-like lip, from the main, load-bearing bridge (6), in the lateral direction, transversely with respect to the longitudinal axis of the main, load-bearing bridge and project beyond the top side of the main, load-bearing bridge (6). They are designed such that their flexibility in relation to the main, load-bearing bridge counter to a bearing force, usually the locally active weight of a mattress which has been positioned on top and of a person who is resting on said mattress, is more yielding than the flexibility of the main, load-bearing bridge itself. The spring-bridge construction proposed, on the one hand, permits cost-effective production of a spring-bridge grille and, on the other hand, nevertheless provides the functions which are necessary for a high degree of lying comfort, in particular locally progressively adapting spring properties.
