The purchase of this 7 zone slatted frame was well worth it, right the first Einliegen I could feel less pressure on my back is exercised. I am side sleeper and was several operations on the spinal column. My Ortophäde recommended me to switch from the water bed for 7 zone slatted frame with flexible adjustable disc springs. Even my partner, who have ordered the slatted frame is the same, is satisfied with the quality of sleep and no longer complains about lack of sleep or pain.
