In order to garantee a maximum of lie comfort a down suspension has to be in place. In gerneral it can be said that for a latex- and foam mattress a slatted frame with at least 28 slatted wooden strips should be inserted. In addition to that a functional and adapted slatted bed base is essential for a fine sleep. The basis are multiple glue-laminated elastic slatted wooden strips and a core-board. Added to that there are sliders to regulate the degree of hardness. Very high lie comfort is garanteed when using a motorised adjustable slatted frame.
