The Clina bed's structure is made of steel tubing with a wooden headboard and base. The back support evolved from a system we designed in 1988, based on canvas deck chairs. Ergonomic properties include support for the back on a flexible surface that follows the body's curvature, minimizing any inconvenient tendency to slide forward. The wooden headboard is used as a means of setting the support, with hinges to turn and move the leather surface to the front. A steel bar in the hem functions as counterweight when folding, or a means of locking the back support when in use.
