roviva System Frame butterfly flex K

Every roviva butterfly mattress shares the same foundation: the butterfly flex system frame. It feels noticeably strong yet velvety underneath you at the same time — a result of its ergonomic shape that doesn't cost it any stability.

How the butterfly frame is built

Instead of rigid support points, the frame uses self-regulating articulated springs that move freely and give the lying surface an anatomical shape. Because the construction extends beyond the actual frame, the surface stays 100% flexible right out to the very edge. Height adjusts in stages so the pelvis and lumbar area can be fine-tuned to your body, and the firmness of each individual slat can be adjusted too — whether you prefer more support or more give.

Relief for side sleepers

When your shoulder sinks in as you lie on your side, the springs right at that spot give way downward, opening up space. That takes noticeably more of the unpleasant pressure off your shoulder.
