Conventional beds have a spring mattress and a sprung base for the comfort of the user, but on profiling beds, a sprung base cannot be used and, ordinarily, a mattress is laid on lifting and lowering mechanism, with a result that when pivoted or folded, folding or rucking of the surface of the mattress occurs to the discomfort of the user. A first object of the invention is to avoid the above disadvantage, and a second object is to provide a body support arrangement of greater comfort than conventional mattresses and separate bases. The first objective is met by a body support arrangement comprising at least two sectors connected in such a manner as to permit a relative pivoting of the sectors with respect to each other, each sector being formed by an upper sprung or filled mattress part and lower sprung base part. Preferably, the body support arrangement comprises three sectors, each sector being hingedly connected to an adjacent sector, to allow each sector to be so angularly positioned to suit a users required body and leg dispositions. At the pivot area between the mattress parts of the sectors, a filling of a resilient and compressible material may be provided between the springs. The second objective is met by a construction comprising an array of springs, extending between upper and lower surfaces of the support arrangement in spaced relationship in the longitudinal and transverse directions, the spaces between at least some of the springs being filled with resilient and compressible material. The filling preferably extends over the full length and width of the arrangement, and further, preferably, is in upper and lower layers with through holes into which extend the upper and lower ends of the springs respectively.
