Adjustable wooden frame to allow selection of the desired sleeping position. Slats in natural steam pressed Beechwood. Flexible slat mountings guarantee optimum support for the natural posture of the spine. Rigidity regulation in the lumbar region enables personalisation of the support level and the special red slats have been developed to optimise support in the critical area of the shoulders and cervical zone. The unvarnished wooden structure does not contain formaldehyde and is completed by removable wooden legs.
