This guest mattress will ensure that your guests won't want to leave anytime soon. With a sleeping surface made of 4 cm of visco-elastic mineral foam, it offers heavenly sleeping comfort. The open-pored and breathable mineral foam becomes softer with body heat and perfectly adapts to body contours. And it does so anew with every change of position. A noticeable pressure relief and perfect support for the optimal sleeping position are guaranteed with this mattress. In no time, the soft mattress can be folded into a cube and serves as a lumbar support cube in this format. Lie down on the floor for exercises and place your legs bent on the cube. In this position, you relieve the intervertebral discs, allowing them to regenerate. The cube can also be optimally used as a comfortable seating cube or as a table. To avoid unnecessary packaging and enable easy transport, the guest mattress is delivered vacuum-packed. Additional details: Cover: 100% cotton, washable at 30 degrees, core: 11 cm polyurethane, 4 cm visco-elastic mineral foam, cover color: black.
