The top layer of the three-layer mattress is made of viscoelastic foam and provides even pressure distribution. It moulds itself to the body shape of the patient without restricting their mobility. The middle layer of the TriOptima® mattress is made of breathable, fulled polyurethane foam, which prevents one from sinking too deeply into the mattress with its high density and low compression hardness. The lower layer consists of cold foam - it is the load-bearing layer and fixes the mattress with an anchoring system on the slatted frame in order to optimally integrate the mattress into the motion sequence of the RotoFlex®
