The Grecale mechanism is CATAS-certified. By easily rotating the back and subsequently unfurling the mechanism, it turns into a comfortable bed without having to remove the cushions on seat and back. The high-tensile steel mechanism is made with a supporting frame already fit with bayonets for quick assembly of the arm- and backrests. The orthopaedic bed base is sturdy, stable and comfortable, particularly suited for frequent and daily use. Comes with wide slats and double slats. Elastic straps or the electrically welded panel can be mounted in the seating surface at the customer’s choice. The Grecale mechanism, certified by CATAS, can accommodate a wide choice of comfortable, 14 cm thick polyurethane and memory foam mattresses.
